The sum of two numbers is 5: x + y = 5
The difference of the numbers is 39: x - y = 39
Your equations are:
x + y = 5
x - y = 39 add the two equations
--------------
2x = 44
x = 22
Plug 22 in for x in one of the original equations and solve for y
22 + y = 5
y = 5 - 22
y = -17
Your numbers are 22 and -17
