To solve the equation 2(x + 9) = 16 for x, we need to perform the following steps:
1. Distribute the 2 to the terms inside the parentheses:
2 * x + 2 * 9 = 16
2x + 18 = 16
2. Subtract 18 from both sides of the equation to isolate the x term:
2x + 18 - 18 = 16 - 18
2x = -2
3. Divide both sides of the equation by 2 to solve for x:
2x/2 = -2/2
x = -1
Therefore, the solution to the equation 2(x + 9) = 16 when solving for x is x = -1.
