i was panicking for my maths test tomorrow and spent like 50 years going over websites and my teachers slides until i found this legends video that explained it so simply. cheers.
You got this!
what'd you get on it mate
Why did my instructor become angry when I asked to repeat some of the steps?
Mali Rabbit that’s because your instructor is somewhat rude. Teachers are supposed to answer school relevant questions without judging or becoming angry at the student. I hate it when my teachers do that.
thats because the instructor doesnt know it himself without a script
Some teachers just don't want to redo those like my father
Cuz he is a piece of crap
He's underpaid, going through a divorce and his kids want nothing to do with his ass
this was prolly one of the most helpful videos, thank you
went through like 10 videos this was the most clear thanks :)
Thanks!!! I always go to your channel to learn after school everyday!!!

Nerd
shut up ur all neeks
At 3:19 what if we dont have the same numbers with “y”?
As a Mom of a 5th grade son that can do this math, I’m extremely proud.
Thank you this helped me solve my equation.
Nice trick, keep the good stuff up👍
yo man you a real legend bro you literally saved me like 5 hrs of time and also you saved me for my test tomorrow. thank you so much.🙏🙏🙏
You just made it very simple 🙏💯
oh ma gawwd thank you, I was stuck on one of these and thought I have to spend an hour going through videos telling what I already know but I'm glad I clicked this one first, :)
Glad I could help!
This guy is actually insane - in a good way
So helpful, thanks! 👍
I like this style of solution. Thanks
Amazing! Thank you so much
wow sir you make the best explanation ever
Thanks very much. This was a difficult topic for me but you made it easy
Great video.
this really helped me thx 😃
Thanks so much
Thanks,l now understand
Thank You!!!
You're welcome!
Hi tech math, last time I commented was you showing how exponential growth related to cov19 about 3 months ago. I think you're an aussie or kiwi. You showed up this morning on my noti. How are things? Well we're kinda in limbo here in the US. I think it's all about the elections and a vaccine at this point. Your country did a great job, ours...🤔. I resubd just to get a noti again. Wishing you well and glad to see you on my list again. Be safe.
your accent let me focus very well. thank you 🙏
I’m not in school anymore I am watching this for fun
You're a psychopath
oh
- said no one ever
Me 2 reminding myself to keep that knowledge
Ur not human if ur not lying
Thankyou sir
Voice quality is perfect
Love watching your videos, very easy to follow and infomative. Need some help, how to solve 2.4×10^5 over 3×10^2 and 5×27^3=5×3^x fast and easy XD thanks in advance :) keep the vids coming 👍
Cringe
@@Penigale how is that cringe?
L bozo not smart enough
8×10^2 first answer
Saved me bro 🙏
Thanks
Great!!! 👍🏽
Thank you! Cheers!
tecmath you’re welcome 😊
excellent
Thanks!
When Thor starts math tutorials 😂, you're voice is like Chris Hemsworth's
I’m watching cos of Kumon

Glad to know that multivariable equations aren’t so difficult after all.
Thanks. As long as you remember to reduce to two equations with two variables no worries.
1:48 is it always the absolute value of the coefficient in the variable you picked to divide the other equation?
How do I tell whether some simultaneous linear equations in 3 variables have infinite or no solutions?
Linear equations will have no powers. They will also match the amount of lines with number of variables.
pop off tecmaths
how do you get the X 4
im still confused
Use Cramer's Rule!
your Z is actually -5 since you will move it to the right side it will be negative so 11 - 16 not 16 - 11 :)
You will be left with -z =-5, so z =5 is correct
Sir how to solve this
x^2 - 16? Plss
its hard a first but i sorta got the hang of it
If I am your student,remember to print notes including formulas? But,when I have pressure you cannot scold me
i wish i was smart in maths
Keep working. Work trumps natural ability in math in the long term
is this the real life?
lovely vid, audio quality could be better
ur face quality could be better
Well I guess I substituted my way out😂
Thanks for the video but I think the voice is too low
Then turn your volume up
What if the 2 z are both minus then what
4,
2,
5
I think you're wrong when change -16 to other side it's = -4 not 4 sir
WHY - WHY do people put up examples using z instead of another letter that doesn't require them to put an extra line through it to distinguish it from the number 2 ? And yet- they put a line through the seven that doesn't even need it? It's too easy to forget the line through the z which could be confused with a two. Or, the horizontal line could turn into a negative if it's written carelessly. Eliminate it all together- don't use the letter z. Less is more.
3x + 2y - c = 11
2x -3y + c = 7
5x + y - 2c = 12
7 looks like 1, also why are u so mad lmao
or you could use... matrices
Not the M word 😱
Sorry but the audio quality is really really poor
i’m so bad at maths
I'm 11

I don’t have the slightest clue what this is all about. The teacher seems to randomly apply numbers out of the blue. Guess I need a tutorial.
Warum Englisch ya kalb 😊
wtf
Lost you after 5 seconds.
lol
