Answer 1

To solve the equation \(-4(z + 12) = 36\) for \(z\), follow these steps:

1. Divide both sides by \(-4\) to isolate the term inside the parentheses: \[ z + 12 = \frac{36}{-4} \] \[ z + 12 = -9 \]

2. Next, subtract \(12\) from both sides: \[ z = -9 - 12 \] \[ z = -21 \]

Thus, the solution for \(z\) is \(-21\).

The correct response is: −21.
