To solve the equation \( \frac{m}{8} - 4 = -12 \), we can follow these steps:
- First, add 4 to both sides of the equation to isolate the term with \( m \):
\[ \frac{m}{8} = -12 + 4 \] \[ \frac{m}{8} = -8 \]
- Next, multiply both sides by 8 to solve for \( m \):
\[ m = -8 \times 8 \] \[ m = -64 \]
Thus, the solution is:
\[ m = -64 \]
So the correct response is \( \text{m = -64} \).
