To solve the equation \( 8 + \frac{b}{-4} = 5 \), follow these steps:

1. **Subtract 8** from both sides of the equation to isolate the fraction:
   \[
   \frac{b}{-4} = 5 - 8
   \]
   \[
   \frac{b}{-4} = -3
   \]

2. **Multiply both sides** of the equation by -4 to solve for \( b \):
   \[
   b = -3 \times -4
   \]
   \[
   b = 12
   \]

Thus, the solution is \( b = 12 \).
