To solve the equation \( 3a - 1 = 8 \), follow these steps:

1. **Add 1 to both sides** to isolate the term with the variable \( a \) on one side of the equation:
   \[
   3a - 1 + 1 = 8 + 1
   \]
   \[
   3a = 9
   \]

2. **Divide both sides by 3** to solve for \( a \):
   \[
   a = \frac{9}{3}
   \]
   \[
   a = 3
   \]

So, the solution is \( a = 3 \).
