To solve for z, we need to isolate z on one side of the equation.
First, distribute -4 to the terms inside the parentheses:
-4(z + 12) = 36
-4z - 48 = 36
Next, add 48 to both sides of the equation to eliminate the -48 term:
-4z - 48 + 48 = 36 + 48
-4z = 84
Finally, divide both sides of the equation by -4 to solve for z:
-4z/(-4) = 84/(-4)
z = -21
Therefore, the solution for z is -21. Answer: -21
