Let x and y be the numbers x+y = 13 x-y = 4 add: 2x=17 x=8.5 x+y=13 8.5+y = 13 y = 13-8.5 = 4.5 The numbers are 8.5 and 4.5

x + y = 13 x - y = 4 ------------- 2x = 17 ---> x = 17/2 (or 8 1/2). The numbers are 17/2 (8 1/2) and 9/2 (4 1/2). *If you are looking for integer solutions, there aren't any.*
