To solve the equation \( 4y - 9 = 15 \), follow these steps:

1. **Add 9 to both sides** to eliminate the -9 on the left side:

\[
4y - 9 + 9 = 15 + 9
\]
\[
4y = 24
\]

2. **Divide both sides by 4** to isolate \( y \):

\[
\frac{4y}{4} = \frac{24}{4}
\]
\[
y = 6
\]

So, the solution is \( y = 6 \).
