To solve the equation \(-3x + 15 = 42\) for \(x\), follow these steps:

1. Subtract 15 from both sides:
\[
-3x + 15 - 15 = 42 - 15
\]
Simplifying gives:
\[
-3x = 27
\]

2. Divide both sides by -3:
\[
x = \frac{27}{-3}
\]
Simplifying further gives:
\[
x = -9
\]

Thus, the solution for \(x\) is \(-9\).
