To solve the equation \(-\frac{3}{5}(15x - 30) = 198\), follow these steps in order:
-
Distribute the \(-\frac{3}{5}\) to both terms inside the parentheses: \[ -\frac{3}{5} \times 15x + \frac{3}{5} \times 30 = 198 \] This gives you: \[ -9x + 18 = 198 \]
-
Subtract 18 from both sides to isolate terms involving \(x\): \[ -9x + 18 - 18 = 198 - 18 \] This simplifies to: \[ -9x = 180 \]
-
Divide both sides by -9 to solve for \(x\): \[ x = \frac{180}{-9} \] This simplifies to: \[ x = -20 \]
Thus, the correct order of steps is as follows:
- Distribute \(-\frac{3}{5}\).
- Combine like terms (subtract 18).
- Divide by -9 to solve for \(x\).
