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

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

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

Simplify:
4y - 8 + y = 2
