Solve the equation using inverse operations.

1/3x=−9 (1 point)

1 answer

To solve the equation \( \frac{1}{3}x = -9 \) using inverse operations, follow these steps:

  1. Identify the operation on \( x \): Here, \( x \) is being multiplied by \( \frac{1}{3} \).

  2. Use the inverse operation: The inverse of multiplying by \( \frac{1}{3} \) is multiplying by its reciprocal, which is 3.

  3. Multiply both sides by 3:

    \[ 3 \cdot \left( \frac{1}{3}x \right) = 3 \cdot (-9) \]

  4. Simplify both sides:

    \[ x = -27 \]

Thus, the solution to the equation \( \frac{1}{3}x = -9 \) is:

\[ x = -27 \]
