Answer: 22

Explanation:

Solve for x

1/2x + 7 = 18

Combine 1/2 and x.

x/2+ 7 = 18

Move all terms not containing x to the right side of the equation.

Subtract 7 from both sides of the equation.

x/2= 18 − 7

x/2 = 11

Multiply both sides of the equation by 2.

2 ⋅ x/2 = 2 ⋅ 11

Simplify both sides of the equation.

Cancel the common factor of 2.

x = 2 ⋅ 11

Multiply 2 by 11.

x = 22
