Wow such an amazing website but not useful for me because i am in o level......☺😇🤓
Math is only hard when the teacher fails to teach.
so relatable
Or when you are absent
Yes
very true
THANK U SAY IT FOR THE MR GIBSONS IN THE BACK
This is honestly easy, but the thing is, our teacher likes to take away variables or make it confusing during tests. The examples he gives are easy, but the quizzes makes me want to bang my head on the wall.
same my teacher puts confusing problems and i'm about to have my final! help meee
@@miley9455 bro me too omg good luck! tell me how it goes
@@sunrae1825 lol i got 100! thanks
@@miley9455 DAMN i wish i was u I'm taking my final today pray for me lol
@@zenji4746 pray for me final is tomorrow!!!!
You need to teach my teacher how to teach
BigBoiBrandon I agree
Samee
My teacher left half way threw the year and left the new Teacher behind by months took all the hw I turned in then FUCKIN quit. And she got another job but higher up in math like calc
i agree lol
BigBoiBrandon teachers are braindead just use the internet
What he teaches in 10 minutes, takes my teacher over and hour to teach, and I end up learning more from the vid
kaitlyn C-G no it’s just because some kids are really dumb to understand so teachers have to repeat the same shit over and over again and make up different bizarre ways to do these so the dumbshits will understand it but it becomes even more confusing for all of us I feel you.
@@rainbaiyu well lets not say they're "dumb". some ppl are just slow learners but they'll get there. although, i do agree with u. ppl dont wanna study or listen (which is pretty annoying) so they miss out nd they'll have to ask from the teacher which is techanically their fault. but let's not call them "dumb" ty!
Nah it takes her a week
I get you
My teacher doesn't even teach, she just gives us a packet and we work all of the problems together. No explanation beforehand.
Bruh I see all 8th grades here and I'm a junior 😳 that has a quiz tommrow
Edit: currently unemployed life is way harder than equations
Edit recent: Returned to GOD working and studying a course keep going its possible💪
Literally I’m freaking out lmfao I forgot how to do this
junior gang junior gang
same, currently panicking.
Lmao I started watching this cause my state mandated it, but I was never taught it XD
sameee lmao
My teacher likes to go through each equation like it’s a speed run, which is hard for me to differentiate how to do each specific equation the correct way, much less I have a hard time learning with his style, so this video is a life changer
Same I hated my math teacher from 8th grade cause she would speed run and end up not teaching me anything
My teacher right now, he goes through everything so fast and we're all trying to get notes lol
literally me. he just does the equation, solves it, and somehow expects us to know step by step how to do it perfectly im literally so frustrated everytime i walk into that class
same my teacher always goes so fast does 3 exampels in the speed of light and expect us to know it all
Have a test tonight and was having trouble understanding these math concepts, your video made it easy to understand. Thanks
Are you in 10th?
@@nakaylahsmith7356 i am and I literally found this video because I have mid terms first period for math!!!!
yoo am in 7th

this 10 minute video taught me more than a 50 minute algebra lesson smh
can you teach me rn?
fr, my algebra teacher literally spends 30-40 minutes ranting on about Black Coffee, bridges in China, eruopean currency, politics, in fact sometimes we don't even learn algebra at all! (this was 3 years ago) and it was definitely an interesting class
facts
Exactly
@@wr245g9 he didn't respond 💀
this guy rlly taught me more in 10 minutes than my math teacher has taught me in 3 months
edit: I was the only kid who got 100% on my test tysm
Yay congrats
Congrats bro
WOW IK IM 1 YEAR LATE BUT CONGRATS!!
Congrats, 2 years late lol
3 years late lol, but congrats anyways
Elimination/Addition Method
Example 1 - 0:01
Example 2 - 1:37
Substitution Method
Example 1 - 3:53
Example 2 - 5:56
Example 3 - 7:29
Your a fucking legend
Thanks
Thanks
Thank you, I thought I had to go through the whole video.
THANK you
I've been really struggling with substitution in my 8th grade math class right now, and I think I'm finally getting a grasp on how to do it! I used to dread the days we'd do substitution. I still love elimination a lot more, but my anxiety has been getting worse with the stress of not understanding substitution and I really think it's clicking in my brain now! You're a life saver - thank you!!
im in 8th grade studying for a test tmr
Bruh why duh hell are all of you 8th graders I'm a goddamn freshman.
@@meatballman4329 they older than you now lmao
Yah kind of funny I may be late but 5ge reaction is still the same.
@@meatballman4329 what does that even mean
I haven’t been in school for ~8 years and I’m studying really hard to score well on my ASVAB for the air national guard. You have helped me TREMENDOUSLY with stuff I had long forgotten about and are getting the cobwebs off of my brain. Seriously thank you so much.
Hopefully you do good on your ASVAB!!
Same here, trying hard to study for my airforce asvab
@@forestdoughty36 what MOS are you going for? I’m striving for fire safety which is only general but obviously I want to score good in every category in terms of cross training and stuff. People have been telling me to just really focus harder on what is under the general score versus the other areas though to prevent burn out and info overload
same here except i never learned any of this and im not even in the air national gaurd
@@fattud615 “the capacity to learn is a gift; the ability to learn is a skill; the willingness to learn is a choice” keep on learning it’s a super power!
Just gonna say, if it wasn't for these videos, I would have already failed college.
Justin Herb you in math 21?
EXCUSE ME WHAT COLLEGE!?!?
IM IN 8TH GRADE LEARNING THIS
Jim Renzo C. Lapid Lucky, I am learning it in 11th Grade right now.
i learnt this in grade 6, wtf is wrong w y'all school systems?
@@weehee7113 that is exactly why I thought, and if they notice about schools in other countries, they would go crazy
Thank you, my math teacher complicates things and I hate it
Same
You took the words right out off my mouth.
When the shit am i ever going to use this in any situation
College
College dipshit
@@obnoxiouslisper1548 screw collage at most i would take some classes but collage is mostly one big ass blast
@@shrippie-4214 honestly, the school system is stupid anyways, they should teach Kids how to teach themselves and make them independent, Youre fine as long as you have an interest you would like to Invest time in, for example, i like matemáthics and the theoretical parts of computer science (Im not much of a pragmatist). You shouldnt have to worry about not understanding maths if you dont like it. Just be sure to spend time doing what you like, and Also be sure to have fun.
@@obnoxiouslisper1548 yeah being home schooled most of the time i had to
teach my self so i probably have a better education then most people who went to public school
I literally act like I'm taking notes in class and then come take notes from these videos. It's SO MUCH EASIER!
Should start doing this
@@nikztips3096Definitely, that's what i'm doing right now. Just get a notebook and if you want some colored pens to color code some notes! It'll be worth it in the long run man.
@@georgeryandev2103 thanks :) have a good day
Who is in 2024 who has an exam tmr ?
Me
I only came here for studying but sometimes for exams
Over quarantine, I feel like I am slowly forgetting things! Thanks for helping me restore my brain cells 🙏
I have a test tomorrow on this anddd this helped me understand thank you so much!! 💚
How did you fare in your test ?
I can't pay attention in school so you are literally the only reason I'm passing 7th grade math‼️
Hon i am a 9th grader and you are learning this in 7th grade. Dangggg
@@laurenelias301 yeah most people learn algebra shit in 8th or 9th, ive never met anyone doing this in 7th grade lmao
@@ryank09 Dude people do it in 5th also I am only 6th, But to do it in small grades u need a teacher like organic chemistry tutor
@@nishitbijaka308 bro u doin algebra but you gotta pay more attention in english that shit made NO sense
I mean it depends on the school and how advanced the student is
This is waaaay better than my curriculum, thank you so much. My teacher goes way too fast and there isn't a pause for me to really grasp the ins and outs of each concept. He only gives one or two examples and I rarely understand it.. This helps a ton, thank you🙏
My old math teacher used to say "Math is easy, people make it hard." This truly proves him right.
Thx for no long intros and just getting straight to the math. I don’t have time for that kinda stuff
it’s so over for me like i get it but i don’t
*When you have a test related to this*
I don’t understand at all. 8th grade math hard🤦🏾♂️
Boah Ashamed keep practicing
I'm taking it in 9th grade and it's not that bad but yeah keep practicing
Thank God that I'm doing algebra 1 for 8th grade. Didn't had to do these problems
I dont think math itself is hard, it's just the way math is taught in public school sucks.
I tend to forget and since there is no school for weeks I need to remember the last lesson I was on
Bro im so thankful for you, my teacher didnt know how to teach this properly but you did in minutes.may everyone have a teacher like you because i needed you at this moment. thank you so much!!!
Ikrrr 😭
@@kluerbies 😭😭😭😭
who else got a test in 30 minuets?!
😂😂😂 same here
im a freshman in highschool and were doing this right now in algebra 1 and im currently failing that class. the way that my teacher goes through things is a little fast and im scared to ask questions because i may be holding back others. this video helped me and i hope that my grades go up the more and more we continue learning this. thank you!!
i wish this guy was my math and science teacher at school 💀
this guy is goated.. he explained it more clearly than my math teacher who took 1 hour to explain but I still didn't get it, however, THIS guy made me understand it faster in just 10 minutes!! just wow.. I'm out of words man, thanks a lot.
you sir just gained a subscriber :)
FRR
This guy is literally always my go-to whenever i need help with math. He literally never fails to make me learn!
i just have a hard time knowing when to apply which procedure to follow.
TheMJT515 alright so when y is a single variable you apply substitution but when y has a number infront of it you apply elimination, if y has a number infront of it and you can’t apply elimination you divide all the other ones in the equation by the number y has so y will be a single variable. Example: 3x+5y=20. You divide all of them by 5 so it will be y=4-0.6x. Then you just apply it to your other equation like 4x+10(4-0.6x)=12 or something yeah.
@RK rain=99IQ
@@rainbaiyu thank you for replying.
U need to practice it's berry EZZZZ
I was feeling rly depressed & sad bc I couldn't remember how to do this in class and felt like a dumbass. But I started to understand it better bc of this video and in a weird way cheered me up a little. Thank youuuuu.
How the math teacher teaches us : 1 hour
Our friend when we asked him :
Im a freshman in college getting ready to take a test over this stuff today 🙃. Math has never been my strong suit as made clear by me being in such a low level in college. This video has honestly helped a lot. My professor expects us to know everything and like, im not good at math, nor is everyone else in the class... thats why we are in that class, but she doesn't seem to care all that much.
I left high school 5 years ago and haven't used a lick of math out in "the real world" and now I'm starting at a community college and of course I have to learn all this stuff all over again just because that's what they want you to do, even though I know for a fact that I will not use this information. It was a strong suspicion in high school, and now it's basically a proven fact. For most occupations, basic algebra is thoroughly irrelevant.
Thank you so much for this video. I’m studying really hard to get a high score on the GED math test and with this topic I was having a pretty hard time. Now, thanks to you, I feel pretty confident on what to do when I get presented with a situation like these. Thank you again !!!
I wanna thank you for your video's!! The older one's really help me trough these dark days of exams here in Belgium!! Greats from an industrial engineering student from the University of Ghent in Belgium!
Oh man
I didn't realize it was so simple cant focus in class so this helps
Thank you for teaching me when my teacher never did, always head straght for your channel for math and physics lessons. Very helpful :)
The worst part of these videos are the painfully truthful ads for tutoring that come on in the middle of it 😂
RIGHT lmao like why they stalking me😭
I've been cramming for a placement test to go back to school and your videos have helped TONS. I was so overwhelmed when I looked at the practice tests, but your videos plus the website symbolab have been such a huge help. Thanks so much and good luck to everyone else learning!
Thx mate this helps a ton, it not like the other videos where the teacher sound's like they want to jump off a cliff while they skip over all the important detail's because they understand it already.
i have a test tomorrow and this video helped me a lot, god bless you
This is way easier than i expected thanks to you!
Thanks for making this! I forgot how to solve systems and needed a refresher and this totally worked!
My 8th grade son needed help with homework. I haven't studied these subjects in decades. These videos are extremely helpful. Thank you for refreshing my memory on these concepts.
i like how he says 3, and also very helpful as always hope your voice may reach millions of millions of people one day! May god bless you and your family friend, this is literally gonna get me in a much better place :)
Thank you for making the steps simple and easy to understand. I liked and subbed.
A while back I didn't really get this lesson and was relying more on my friends to help me understand this lesson but then, a few nights before my second quiz I watched this video and did all the equations on a paper. I wanted to pass this quiz badly since I did bad on my first quiz. I sat on my desk while answering the quiz and I couldn't help but remember this video. A month after the test was taken, it was given back. I had high and low hopes for my quiz (I was even praying to just get a double-digit mark) I took my paper and noticed my teacher looked at it before smiling. I didn't want to check my paper for at least 3 minutes but I saw the check marks on the back part of the paper. 20/25 !!! It was my first time passing a math test that semester and it was all thanks to this 10 minute video.
I just want to thank you for this video. It saved me from failing a test. I missed several classes and couldn’t understand this stuff and you taught it so well. Thank you.
Thank you, I totally forgot abt systems of equations and I have my final exam tmr!
Thank you!! I haven't done this in years, and I had a chance to try it at a conference. It was bothering me that I had forgotten how to solve these & you made it very easy for me to refresh my memory!
Just went from a B+ to an F in a week because I didn't understand this at all. Now I'm here trying to learn this so I can retake the test and turn in all the assignments I didn't finish late
I never understood this in class but I finally get it now XD It took me about half of the video to finally get it, but I did it! Thank you
I got my test tmrw wish me luck.
So how'd the test go?
Fr how’d it go
What did you get?
@@Nolan_889 i got a 99
@@cornerdust798 it was good i think? this was a year ago lol
I LOVE THIS VIDEO! I LOVE YOU! AND I LOVE JESUS! Thank you soooo much for this video and the step by step instructions!
Had a hard time doing these equations for school and I’m so glad I took notes and followed along with you and now I understand more of it! Thank you
Thank you so much, This video is so old yet so useful! I've been studying with my math teacher but she fails to teach me, why? I've learned this for a year or two and still not understand. I've watched this video just twice and already learned everything I need to know, and now I can get a good score in my test! Thank you, best math teacher in the world is only one and that's you for sure
Not sure if you still check these comments, but just know your videos are still much appreciated! I’m having to teach my son grade 10 math because his teacher isn’t, and your videos have been incredibly helpful for us both! As an aside, I find it funny/sad that, when I went through school and asked ‘where will I ever use this’, no one mentioned that I would use it when I had to teach it to my own kids in the future! 😂🤦♀️
God bless you The Organic Chemistry Tutor. Whenever my class starts to learn about a new subject this is the place I look for. Thank you for helping the people who are new to these subjects not only me but everyone else. God Bless You and keep up the great work.
I'm in 6th Grade and this is extremely helpful for me.
Peace be upon you! I'm in 7th and this is really helpful I have a quiz about this so I hope hope I get good marks
online school sucks but you just made it a lot easier for me, thanks mate.
I love this guy so much!!! He made my life so much easier. Keep it up man
The organic chemistry tour, the channel that makes math easier so Baldi won't slap you with his ruler.
All you have to do is
Thank god I found this video I’m about to take my math test
This is more effective than online classes. And this video was 10 minutes. I'm at school for 6+ hours online everyday and would've still been struggling if it wasn't for this video
This man is the best math teacher I’ve ever had!
YOU SAVED MY LIFE THANK UUUUUUUU
im currently watching this while taking a quiz
POV: you have your algebra 1 midterm in three days so you are desperately watching videos on what’s on it
This taught it to me way better than my teacher did, thanks so much, very useful!
Thanks for this I hope you make more tutorial
last minute study fr
Thank you so much for making math easier to understand for us. It’s a really big help especially many teachers we have don’t really care whether their students actually learn something. Looking forward to more videos💕🇵🇭
words can’t express how many times this man has helped me with chemistry and math problems keep doing what you do man your saving millions of lives and future careers❤
I got an ad for a Math learning app called Study Pugg while watching this......
same
Thanks, I’m slow when it comes to math I’m In my senior year if I don’t pass this year I’m fucked helped me understand it in ten minutes when my teacher couldn’t in the course of 3 weeks
I was struggling so hard on this in class and when I finally realized what I did wrong after watching this, it put the biggest shock of realization on my face. Thanks so much 🙏 💓 ☺️ 💗 💖
I really appreciate this man so helpful in every way and much more understandable than i thought
Thanks man.. your a real life saver, honestly I wish you were my teacher…
fr bro he makes things so much easier 😭
while following this tutorial for my homework i was literally close to killing myself... not irl... ALGEBRA IS SOOO HARD! but overall this video was very helpful.
Not irl? So you mean in Minecraft of smthn?
Haha wait till u learn calculus.....
Thanks a ton! I had to refresh my math and graphing skills for macroeconomics and this was very concise and easy to understand. Left a thumbs-up!!
Thanks a lot man, this is gonna help me a lot for my test tomorrow, my teacher didn’t explain this stuff half as good as you did :)
in 1:36 minutes you have taught me more then my teacher could in 3 days
2:36 why did he divide the 2nd equation by -2? i don't get it
I can finally say I know how to do these problems now. Thank you so much.
Bro, your explanations are much better than our math teacher! Appreciate this! 🙏
I have an assessment tomorrow and I literally didn’t understand anything before this video
Honest question, where do you teach? I know you do. What school? I wanna in role.
Me too
@@nishitbijaka308 hey nishit long time man! Remember in elementary school how much fun we had it was a blast! What school are you going to now?
@@ishaan6621 Actually i am just so happy u remeber me and we did have a blast. U talking bout sommeville right
I am apparently in banglore
Give me ur email if u are seeing this cause if u found me lets stay connected
Thank you so much! I have a test tomorrow and I didn't understand the concept at all so i'm oh so grateful for this video!
My midterm is tomorrow, and legit I had no idea how to do this until now. Thank you Jesus CRIST. My math teacher can’t fricking TEACH
I'm in college and only now learning this 😂 wtf
If you’re here for the same reason I am 7:28 (substitute without Y being in the front ) 🤦🏽♀️ you’re welcome
Thanks g 🥶😤🔥🗣🤮🦍👎🏽🏋🏿🐐💯
Damn bro the way you teach got me feeling like Albert Einstein in class😭 thanks man!
This helps so much especially since school is closed for the rest of the year and now teachers decide to make shit even more complicated then it was before.
what if you can't divide the value of x or y and you're left with an fraction ?
Google
Then the answer is a fraction lol
This helped me memorize..... ninth grade so far is painful, trigonometry and all😭💀
This is way easier than I thought! I understood it in 2 mins instead of 1 hour
Ive had my same math teacher for 3 years and this makes more sense from you than he ever has
