1 answer

To find the value of \( x \) in the equation \(-3x + 9 = -18\), we’ll solve for \( x \) step by step.

  1. Start with the original equation: \[ -3x + 9 = -18 \]

  2. Subtract 9 from both sides to isolate the term with \( x \): \[ -3x = -18 - 9 \] \[ -3x = -27 \]

  3. Now, divide both sides by -3 to solve for \( x \): \[ x = \frac{-27}{-3} \] \[ x = 9 \]

So, the value of \( x \) is \( 9 \).
