# Solving Systems of Equations by Substitution by Shmoop

To unravel programs of equations by substitution simplify the equation to isolate one variable. It does not matter which one however let’s use x. Subsequent, substitute that equation into the variable x of the second equation and clear up for the opposite variable, on this case y. Upon getting y, simply plug it in to both equation and clear up for x.

Thanks

Anyone else listen for an hour in algebra and then watch for 3 min and learn more than clsss

good video, cut out the cringe intro tho

i watch you since 7th grade

I learned nothing

Wow this made it easier than being 2hours in math class…. I learned this is 2 minutes???!!!!!

Were and how the fuck did u get the 5

What if itβs like for example 6x – y

But this shit really helped I got 0 on my warm up but tomorrow I'ma show teacher that I'ma do better I didn't this was that easy the only thing is I can't do 2 step equations those are fucking hard

Why do you have to divide both sides even tho we don't use the other number

Thaaaaaaaaaaaaaaaaaaaaaaaanks

Can't believe I needed to review this in college, lol

How the fuck is the 14 positive and the 72 negative

THANK GOD, YOU SAVED MY GRADE

this video did does not help

this video is going too fast! SLOW DOWN!

im going to keep watching this vid till i get it xD

Plenty of thanks. I learned more here then one hour of class.
