To solve the equation \( \frac{1}{3}(6x - 9) = -33 \), follow these steps:
- Multiply both sides by 3 to eliminate the fraction:
\[ 6x - 9 = -33 \times 3 \]
\[ 6x - 9 = -99 \]
- Add 9 to both sides to isolate the term with \( x \):
\[ 6x = -99 + 9 \]
\[ 6x = -90 \]
- Divide both sides by 6 to solve for \( x \):
\[ x = \frac{-90}{6} \]
\[ x = -15 \]
So, the solution is \( x = -15 \).
Therefore, the correct response is:
x = -15
