What is the solution of the equation 2(x + 9) = 16 when solving for x ?(1 point)

1 answer

To solve the equation \( 2(x + 9) = 16 \) for \( x \), follow these steps:

  1. Distribute the 2: \[ 2x + 18 = 16 \]

  2. Subtract 18 from both sides: \[ 2x = 16 - 18 \] \[ 2x = -2 \]

  3. Divide both sides by 2: \[ x = \frac{-2}{2} \] \[ x = -1 \]

So, the solution is \( x = -1 \).
