Question

Use the substitution method to solve the system

−x+y=−1,
4x−3y=6.

Answer 1

(3,2)

Explanation:

I changed the first equation to x=y+1. Then I substituted the x in the second equation with y+1. So, I got 4(y+1)-3y=6. Then 4y+4-3y=6 turns into y=2. Then you replace y with 2 in the first equation. -x+2=-1. -x=-3 or x=3.
