Let x and y be 2 numbers.

Givent hat their sum is equal to 40.

x + y = 40

Also given that one number(x) is 8 more than the other (y)

Therfore x = 8 + y

Now by back substituion we get:

(8 + y) + y = 40

2y = 40 - 8

2y = 32

y = 16

Now by back substituion we get:

x = 8 + y

x = 8 + 16

x = 24

Thus the solution.
