Answer:
9
Step-by-step explanation:
Locate the point marked 3 on the axis marked y. Follow the horizontal line to the right until it meets the blue line representing g(x). From that point, follow the vertical line down to the x-axis to see the x-coordinate: 9.
x = 9 . . . for g(x) = 3
So if the half larger number is a difference of forty wouldn't one of the numbers be 20?
