Question

Use the substitution method to solve the system.

x + 7y = 7

2x - 3y = -3

Type your answer as an ordered pair. (x,y)

Answer 1

First thing ya wanna do is solve for a variable
so x = 7 - 7y

Then plug it into the other equation (substituting)
like so

So y = 1
And then you plug y back in to find x :D
