To solve the equation \(-4(2x - 11) = 12\), follow these steps:
1. Distribute the -4:
\[
-4 \cdot 2x + 4 \cdot 11 = 12
\]
\[
-8x + 44 = 12
\]
2. Subtract 44 from both sides:
\[
-8x + 44 - 44 = 12 - 44
\]
\[
-8x = -32
\]
3. Divide by -8:
\[
x = \frac{-32}{-8}
\]
\[
x = 4
\]
The solution is \(x = 4\).
So, the correct response is:
**x = 4**.
