I legit thought from the thumbnail it was Jeff bezos

[jjmjpqw]

This makes so much more logical sense than the inverse matrix method! Thank you

[cmayotte]

Thank you for covering every thing Organic Chemistry Tutor hasn't, you two are literally the reason I'm passing 10th grade

[lucamace]

Seeing the thumbnail, I thought you were Dr. Gary Linkov for a second, you two look very similar lol. Great video though, thank you for the articulate explanation!

When 12 moves to the other side it'll be 7-12 which is -5

This is the only video that worked for me after watching all of Organic Tutor videos and not working out 🤦🏽‍♂️

Sir, you said, when you want to solve you first need to look for the equation whose first variable has coefficient of one to tackle before and I like to see if all the variables have coefficient exceed one, how can you be start solving them.

Thank you so much for making this video! It really helped me a lot 😊

THANK YOU SO MUCH U SAVED ME FROM GETTING A BEATING 1:32

Could you solve for any amount of variables? And do you need the same amount of equations to solve?

[surachaisupanaranond]

Great teacher. Another good learning. From Thailand.

[samirayoubi]

hello
There are a few ways to solve linear equations?
Do you have a book on these subjects, dear professor?

[ThatOneGuyYouWontRemember]

3:16, but what if that z has something attached to it?

[takeshi]

Can you use this in solving linear programming with 3 variable to get the result?

[HemdadKurdy-xgpu]

Thnk you you are very good👏سوپاس تۆ زۆر باشی

[okjkruo]

Thanks alot it has really helped me❤❤❤

i live in canada what grade level is this?

In solving for, x - y + 2z = -4 the creator writes ( what looks to me on the screen ) `x = y - 2z - y.
A Mathematician has to make `4` look like "4" and not `Y.`
There`s nothing more precise than Maths whislt at the same time there being nothing more `sloppier` than a 4 looking like a y.
Some of us actuallystop the videos and look for a solution - whilst having no idea what you have written is an 4 or an y. Get it ? As if maths is not diffcult enough without these slops !
You are not for me as a teacher of maths.
