Solve a system of equations with three variables

👉Learn how to solve a system of three linear systems. A system of equations is a set of equations which are to be solved simultaneously. A linear equation is an equation whose graph is a straight line. The solution to a system of equations is a set of unique values of the variables for which each of the equation is satisfied.

Had to skip out on a whole lesson today and you just made this crystal clear in a few minutes. Thank you.

1:11 those ladies better pay attention

I didn’t want to go to college for tutoring. I spend a whole day trying to figure out how do solve variables. I have my teachers notes but your video literally helped me within minutes. Thank

I want to thank you for your videos. I, like yourself, struggled with math in high school and was a straight A student other than math. Now, as an adult in my 30s I am teaching myself advanced mathematics starting with precalculus so I could refresh myself on all the subject matter I have not studied in nearly 25 years and when I got to this topic I would get some right and then some I could not. I FINALLY managed to work through the problem I struggled with (out of James Stewart's Precalculus textbook) and can now confidently move forward. I am considering going back to school online to pursue a career in mathematics and I thank God for you and your way of making things clear. I have no idea what that negative comment was all about as you are anything but "terrible" as that individual said. Thank you a million times from the bottom of my heart <3

I don't understand where you get -2 from to multiply the equation from in the very beginning.

[aleah]

Thank you so much for this video! Very helpful

And we got a 30 sec timer for this question in exam.. How to solve it with matrix.. Please clear that sir

[jomjomjamboree]

That one dude in the back being like “couldn’t you just have added the Y’s together” clearly didn’t pay attention earlier when the teacher asked which one to solve first

Person tried to be a smartass but only outed himself for not paying attention lol

[HSDarke]

you also could've taken equations A and B and eliminated more.

[allyouwannaknow]

Question: can I use substitution all the way from your first step?

[doncorleone]

how about if there is only 2 equations but with 3 variables?

Is this what some math teachers are like? This guy is terrible. He just writes with terrible handwriting in small font at high speed without explaining anything.
