To solve the system of equations given:

1. \( 2x - y = 15 \)
2. \( y = 9 \)

We can substitute the value of \( y \) from the second equation into the first equation.

Substituting \( y = 9 \):

\[
2x - 9 = 15
\]

Now, we will solve for \( x \):

1. Add 9 to both sides:
\[
2x = 15 + 9
\]

\[
2x = 24
\]

2. Divide both sides by 2:
\[
x = \frac{24}{2}
\]

\[
x = 12
\]

Thus, the value of \( x \) in the solution to this system is \( \boxed{12} \).
