To solve for z, we can start by distributing the -4 to both terms inside the parentheses:
-4(z + 12) = 36
-4z - 48 = 36
Next, we can isolate the term with z by adding 48 to both sides of the equation:
-4z = 36 + 48
-4z = 84
Then, we divide both sides of the equation by -4 to solve for z:
z = 84 / -4
z = -21
Therefore, the solution to the equation -4(z + 12) = 36 when solving for z is z = -21.
