Question

What is the solution of the system? use substitution . 4x+2y=10, y=-3x+6

Answer 1

@steve can you help??

Answer 2

It tells you to use substitution and you already have y, all alone on the left. It is (-3x+6)
so
use that. substitute it for x i the other (first) equation

4 x + 2(-3x+6) = 10

4 x - 6 x + 12 = 10

2 x = 2

x = 1

y = -3(1) + 6 = 3
