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 = -3y - 17
2) 2x + 3y = -7

Substitute x from equation 1) into equation 2):
2(-3y - 17) + 3y = -7

Simplify:
-6y - 34 + 3y = -7
-3y - 34...
