To solve the equation \(-\frac{3}{5}(15x - 30) = 198\), follow these steps:
-
Distribute the \(-\frac{3}{5}\): \[ -\frac{3}{5} \cdot 15x + \frac{3}{5} \cdot 30 = 198 \] This simplifies to: \[ -9x + 18 = 198 \]
-
Subtract 18 from both sides: \[ -9x = 198 - 18 \] \[ -9x = 180 \]
-
Divide both sides by -9: \[ x = \frac{180}{-9} \] \[ x = -20 \]
So the solution is \(x = -20\).
The correct answer is: x = -20.
