To solve for z in the equation -4(z + 12) = 36, you need to isolate the variable z. Here's how you can do it step by step:
1. Distribute -4 to both terms inside the parentheses:
(-4)(z) + (-4)(12) = 36
-4z - 48 = 36
2. Move -48 to the right side of the equation by adding 48 to both sides:
-4z = 36 + 48
-4z = 84
3. Divide both sides by -4 to solve for z:
-4z / -4 = 84 / -4
z = -21
Therefore, the solution to the equation -4(z + 12) = 36 is z = -21.
