To solve the system of equations by substitution, we'll substitute the expression for y from the second equation into the first equation and then solve for x. Let's go through the process step by step:

Given equations:
1) -4x + 4y = 8
2) y = -2x - 10

Substitute y from equation 2) into equation 1):
-4x + 4(-2x - 10) = 8

Simplify:
-4x - 8x - 40 = 8
-12x - 4...
