To solve the equation \(-2(3x - 15) = 60\), we start by distributing the \(-2\) on the left side:
\[ -2 \cdot 3x + -2 \cdot (-15) = 60 \]
This simplifies to:
\[ -6x + 30 = 60 \]
Next, we isolate the term with \(x\) by subtracting \(30\) from both sides:
\[ -6x = 60 - 30 \] \[ -6x = 30 \]
Now, we divide both sides by \(-6\):
\[ x = \frac{30}{-6} \] \[ x = -5 \]
Thus, the solution is:
\[ x = -5 \]
