To solve the equation \(-2(3x - 15) = 60\), follow these steps:
-
Distribute the \(-2\) on the left side: \[ -2 \cdot 3x + (-2) \cdot (-15) = -6x + 30 \] So the equation becomes: \[ -6x + 30 = 60 \]
-
Subtract 30 from both sides: \[ -6x + 30 - 30 = 60 - 30 \] This simplifies to: \[ -6x = 30 \]
-
Divide both sides by \(-6\): \[ x = \frac{30}{-6} = -5 \]
Thus, the solution is: \[ \boxed{-5} \]
