Solve for x

To solve the equation \( 7(4x - 15) = 63 \), follow these steps:

1. First, divide both sides by 7 to simplify:

\[
4x - 15 = \frac{63}{7}
\]

This simplifies to:

\[
4x - 15 = 9
\]

2. Next, add 15 to both sides to isolate the term with \( x \):

\[
4x = 9 + 15
\]

This simplifies to:

\[
4x = 24
\]

3. Finally, divide both sides by 4 to solve for \( x \):

\[
x = \frac{24}{4}
\]

This simplifies to:

\[
x = 6
\]

Thus, the solution is

\[
\boxed{6}
\]
