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 \( 2 ( x + 9 ) = 16 \) for \( x \), follow these steps:

  1. Divide both sides of the equation by 2: \[ x + 9 = \frac{16}{2} \] This simplifies to: \[ x + 9 = 8 \]

  2. Next, subtract 9 from both sides: \[ x = 8 - 9 \] This simplifies to: \[ x = -1 \]

So, the solution is: \[ x = -1 \]
