To solve the equation \( 5x - 4 = 20 \):

1. **Add 4** to both sides to eliminate the constant term on the left:
   \[
   5x - 4 + 4 = 20 + 4
   \]
   \[
   5x = 24
   \]

2. **Divide both sides** by 5 to solve for \( x \):
   \[
   x = \frac{24}{5}
   \]

Thus, the solution is:
\[
x = \frac{24}{5} \quad \text{or} \quad x = 4.8
\]
