Using Elimination to Solve Systems
Вставка
- Опубліковано 30 вер 2012
- 👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves making the coefficient of one of the variables to be equal in all the equations that make up the system, in order to eliminate the variable using subtraction (or addition as the case may be). The coefficients can be made equal by multiplying the entire equation with a number which when multiplied to the coefficient of the variable to be eliminated gives the LCM of the coefficients of the variable to be eliminated in all the equations. Then we solve for the remaining variable(s).
After we have obtained the solution{s} for the remaining variable(s), we substitute the obtained solution into any of the original equations to obtain the solution of the eliminated variable.

Who else is watching this bc their teacher doesn’t know how to teach
Hans A my teacher didn’t explain it just gave us to do it for hw :( my brain doesn’t work anymore I’m to young to learn this but oh well that’s how honors is 😔

Lmao got a test tommorrow and the teach just sucks at her job
Im watching this because my teacher is an asshole
Or their mom won’t help them 😣

POV: You're here because your teacher is bad at teaching
It’s not that your teacher is bad at teaching it’s that the way they taught it you may not understand as how much this explanation is universal(for a lot more people).
@@clericspire3440 POV: that’s cap
@@clericspire3440 maybe the teacher should try and engage students in the lesson since thats what they're payed to do. i've had teachers that have helped me understand really confusing shit, and my current one, i cant understand a thing he rambles on about, even when i ask him to go back i barely understand a thing.

Or maybe it’s because i choose to look at the wall and not pay attention then wake up at midnight when your friends are asleep and you can’t get answers off them so you frantically look up a yt vid an this comes up 😳
If this video or many others was helpful, please consider letting me know with a "Super Thanks" above ⬆. I am able to read and respond to all my messages and thank you so much for your support

This is why I am here
I passed thanks to him! btw

yeah>:(
From this moment forth I am no longer paying attention in math class, THIS is my new teacher, cuz my math teacher doesn't make ANYTHING clear, and shes also really mean to us, constantly treating us like we're stupid, and putting us down and im over it.
Heidi Espéranza it has gotta to that point sis . Understandable
I didn't understand a lesson with my teacher(she is kind and loves explaining) but I wasn't able to understand it so I came here and I understand elimination better. Woohoo for me now I can bring my grade up in math.

Brave man being filmed. You have demonstrated excellent communication skills, great patience, a full explanation to the class of the subject, and left nothing to guesswork. Good competent teaching.
Because of you, I passed my pre-calc test! Thank you! God bless you! :)
you are very welcome
Chriza Oyan
Wait...you guys learn this stuff in pre-calc?? What grade are you in...10th? (I'm in 8th by the way..). I thought pre-calc was much more complicated with trig and functions and all.🤷😯
+Chriza Oyan same here bro, I started watching this guy's vids and I'm in 8th grade and Idon't get any of this, and that is why I got a 27% on my test
What if its x+y=8
x-y=-2 idk dis equation i hope u help me
+sarah xx x=6 y=2
I decided to finish my degree after 20+ years out of college. Part of that was taking elementary math (118). Using your videos has been super helpful in that pursuit!
1:04
Congratulations man! Hope life’s been going well!
Nice! Same here. Relearning math after failing it everytime in college lol
thank you!
Why -2 and 3?
Variable X is his chosen elimination (3× and 2x).
-2 (3x) = -6×
3 (2x) = 6x , and now you can eliminate it.
You can pick ANY factors. Make sure the factors you going to pick will produce the SAME RESULT but OPPOSITE SIGNS as you MULTIPLY it by CHOSEN VARIABLE so that you can eliminate it and also don't forget to multiply the whole equation by the factors you chose.
thanks for sharing Rocky!
that was the one confusing thing
What if there are different signs
@@musiclover0184 you can directly eliminate them for example
2x+4y=8
4x-2y=6
Make the values of 2 and 4 the same and directly eliminate. Hope I helped!

my teacher expects us to know everything already and when i am unable to solve questions its beacause i suck at math? if i can easily understand this why cant i absorb anything my teacher says? its because 'she' sucks at teaching
i get u
Do all of your classmates have problems absorbing what your teacher says? She might be teaching too fast and not pacing to everyone in the class. Might not even know it unless someone tells her. Or, as you suggests she can't teach. And you can understand Mr McLogan better at your own pace in a comfortable environment. Some classmates can be a bit precious when they know a subject well and not willing to help. Don't give them the time of day. If this channel helps you through your Maths just stick with it.
Mhmm It’s my science teacher tho, all she give is like one slide of notes and the rest is just classwork or project. Like she doesn’t teach and when I don’t understand anything she’s just like look at the the textbook. I end up learning everything on the internet
Teach: "yea you got a question?"
*silence*
Teach: "yea imma get to that in a second."
Me: "good, I was wondering the same thing"

Taking my algebra semester exam I’m in 8th grade I haven’t finished it yet but tomorrow this video is going to help so much thank you Brian.
Yes!!
@@brianmclogan Im taking the same test this video saved me
Your the best teacher i swear i was having a exam tmr n i got nothing from my teacher but i got u in a sec thank you so much ur so helpful
I honestly learned more in this video than in my online Algebra course I was supposed to do today, it didn't explain things well, but he was so easy to understand that I know know how to do it, thank you
I love how you break the math down, your method is awesome keep rocking rollin. Thanks
will do, happy to help
Thank youuuuuuu soooooo much!!!!! Now I understand
awesome! happy to be able to help you out!
Do you know da wae????

Brian, Thank you for taking the time to record these videos!!! I am a middle school intervention specialist and I have been using your videos to learn about high school math to help my freshman son. You videos are extremely helpful and easy to follow. I am sure you are a great math teacher and your students are lucky to have you! Thanks again!
I was looking for u to send my friends ur videos. I studied via UA-cam n entered exams in 3wks preparation from zero ground. I thank God I succeeded. God bless you
Thank you for helping me have a better understanding of this, I know everything I need to know for my test in two day, you're the best youtube tutor.
happy to be there for you, best of luck on your test
It has been 10 years mr.brain 😂 and this still helps A LOT thank you so much ❤
I literally love this guy, he makes it so simple. I spend two hours in a lectured class and did not know what my professor was talking about because she didn't explain very common necessary steps. The entire class was on the discussion board because we all were lost. I've been watching your videos, because they've helped me in the past. I directed the entire class to watch your videos, the thanks I received were over whelming. I wish every teacher had the skills you have to teach students learning would be so much easier and fun.
Yesterday we were learning this and our teacher got us really confused. I said fuck it and left the zoom meeting, looked it up, and now I know how to to it. Thanks brian.
EXACTLY what I was looking for! So glad I came back to your channel! Thanks for the videos! You are great at explaining! Keep up the great work!
You are very welcome!!
Thank you so much. I’m helping my son with his homework and you just saved us a long night.

Your videos are great Professor Mclogan, your method of explanation is such a bless. Now I do have a better understanding of equations. Keep up the good work.
Can't believe that a video from 11 years ago and only 9 minutes long helped me understand more than my teacher could ever teach me in 1 hour and 45 minutes.
Man my teacher just tells us to copy her and doesn't even explain how to do it. Thank you for actually being a teacher and helping me understand my math
man the way you explain things is just so amazing dude, I'm a freshman in highschool and I struggle heavily with math, but I just aced my test because of this video, man I got a 98 :DD

Thanks a lot! i like individuals who shares their(+) academic knowledge instead of war.Thanks again from Ethiopia.
Im a homeschool mom. This video helped me answer the question of why you add or subtract on these. Thank you very much.
I'm 53 and never passed an algebra class. Ive been learning Algebra and its not horrible. Its amazing what you can learn when you are motivated by love. In my case wanting to teach my daughter.
It doesn't have to be opposite integers( the variables you choose) if the same variables are the same then you would subtract. But I understand why you would have opposite integers so the other variables/coefficients would be positive, but just sayin sometimes it's easier to subtract the equations.
and now i can finish my homework, thank you and God bless you
you are very welcome!
My teacher doesn’t explain it good enough as you do, thanks for helping. 8th grade is rough man.
THANK YOU! by watching your video i’m finally understanding, you teach way better than my teacher, you’re a life saver
