Question

G= 1/2 (w+40) (solve for w)

Answer 1

W= 2g -40 is your answer

Answer 2

w = 2g - 40

Explanation:

g =
`(1)/(2)` (w + 40) ← multiply both sides by 2 to clear the fraction

2g = 2 ×
`(1)/(2)` (w + 40)

2g = w + 40 ( subtract 40 from both sides )

2g - 40 = w + 40 - 40 , that is

w = 2g - 40
