a + b = 49
a - b = 9
Add both together to get
(a+a)+(b-b) = 58
2a=58
a = 29 ◄
plug that into the second equation to get
29 - b = 9
so b = 20 ◄
Check:
29 + 20 = 49
29 - 20 = 9

Let's call the two numbers x and y. We can set up a system of equations based on the given information: x + y = 51 and x - y = 13. By solving this system simultaneously, we can find the values of x and y. Adding the two equations together, we get 2x = 64, so x = 32. Substituting x back into the first equation, we find that y = 19. Therefore, the two numbers are 32 and 19.
