​In the equation shown, what is the value of

x that makes the equation true?



​Enter your answer in the box.

1 answer

To solve the equation \( 3(x + 8) = 9 \), follow these steps:

  1. Distribute the 3: \[ 3x + 24 = 9 \]

  2. Subtract 24 from both sides: \[ 3x = 9 - 24 \] \[ 3x = -15 \]

  3. Divide both sides by 3: \[ x = \frac{-15}{3} \] \[ x = -5 \]

Thus, the value of \( x \) that makes the equation true is \( \boxed{-5} \).
