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

Answer 1

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: \[ x = \frac{-2}{2} \] \[ x = -1 \]

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