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

Complete the statement: x = __.

1 answer

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

  1. First, divide both sides of the equation by 2:

    \[ x + 9 = \frac{16}{2} \] \[ x + 9 = 8 \]

  2. Next, subtract 9 from both sides to isolate \( x \):

    \[ x = 8 - 9 \] \[ x = -1 \]

So, the complete statement is: \( x = -1 \).
