To solve the equation \(-\frac{3}{5}x = \frac{2}{5}\) using inverse operations, we need to isolate \(x\).

  1. Start with the equation: \[ -\frac{3}{5}x = \frac{2}{5} \]

  2. To isolate \(x\), multiply both sides by the reciprocal of \(-\frac{3}{5}\), which is \(-\frac{5}{3}\): \[ x = \frac{2}{5} \cdot -\frac{5}{3} \]

  3. Multiply the fractions: \[ x = -\frac{2 \cdot 5}{5 \cdot 3} = -\frac{10}{15} \]

  4. Simplify \(-\frac{10}{15}\): \[ x = -\frac{2}{3} \]

The solution \(x = -\frac{2}{3}\) means we need to check which answer option corresponds to this fraction.

Looking at the answer choices:

  • A: \(-15 \frac{1}{5}\)
  • B: \(23\frac{2}{3}\)
  • C: \(-23-\frac{2}{3}\)
  • D: \(-625-\frac{6}{25}\)

The answer that matches \(x = -\frac{2}{3}\) is in option C: \(-23 - \frac{2}{3}\).

Thus, the correct answer is C.
