Using substitution to solve a system

👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by substitution, we solve for one of the variables in one of the equations and then substitute for the variable in the other equation and then solve for the other variable. Next we plug in the obtained value of the other variable into the equation for the initial variable we solved for to obtain the value of the variable.

The value of the two variables obtained is the solution to the system of equations.

7 years later and this is still helping me on my algebra quiz

[hayleehall]

An 8 year old video in 4 mins taught me more then my algebra teacher in two weeks.

[dantemorales]

This was 7 years ago and all I wanna know is what is Stephen up to these days

[frky]

What a good teacher. You're like one of these chill teachers that gets into the point instead of jamming our brains. I appreciate everything you teach!

[fpano]

Tell me why this man is like a god and he’s the reason why my grade is at a 95. My teacher got fired for being so bad like please come to my school

[riz]

Thanks man you just saved my Quiz tomorrow wish me luck

[aderze]

I love how his videos are short and not too long like other videos which take more than 10 minutes to explain. I can now understand how to do substitution thanks to this guy. Thank you!

[teague.m]

Watching this after my math quiz.


Welp, I failed.

[cheesybreadp]

The way that you teach is so streamlined. The sense it makes- The sense!! 🙌🏾🙌🏾

[Ok-bbgf]

I literally cannot tell you how much this helped me. I have a module test about this tomorrow. And a unit test about solving linear equations and systems of equations. These videos are the best thing to exist. Keep it up 👍

[BigEjLive]

4 minutes compared to 2 weeks is krazy but i learned it thank you

[larryt.]

10 years later and this is still helping me on my Algebra 1 Test, thank you so much Mr. McLogan

[TheDerpyZ]

My teacher takes like 3 days for this stuff, he does it in 4 minutes

[rahafmohammad]

You explanation is better than all my math teacher thank you a lot

[laylah]

Oh gosh thank you so much! My math teacher doesn’t ever explain anything so it gets really hard trying to do hw with out any explanation on how we’re supposed to do it. Thank youuuu— - —

[suspectrumch.]

THANK YOU SO MUCH! Watched this right before test and wrote your equation in my notes and discovered that I had been doing it wrong all along but instead thanks to you I got 100% on my quiz.

[userwhoiswhatin]

11 years later and i still find this video helpful! Thank you.

[isaacplotts]

This is the most learning I’ve done in math this entire grading period

[cxproductions]

This is helping years later as a slacking off senior, taking CCR Bridge. Thank you so much! Highly recommend if you need help with you Math.

Hi! I really respect that you put up guidelines for your comment section. I have an assignment due tomorrow that I've been putting off, and am having to work on it last minute. This helped both me and my sister, TYSM!
