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
