2(x+9)=16 when solving for x

To solve for x, you would need to follow these steps:

1. Distribute the 2 to both terms inside the parentheses:
2(x+9) = 16
2x + 18 = 16

2. Subtract 18 from both sides of the equation to isolate the term with x:
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, when solving for x, you find that x = -1.
