The sum of two numbers is 76 --> x+y = 76
and their difference is 52 ---> x-y = 52
x+y = 76
x-y = 52
Add the equations
x+y = 76
x-y = 52
---------
2x+0y = 128
2x = 128
x = 128/2
x = 64
Use this to find y
x+y = 76
64+y = 76
y = 76-64
y = 12
So x = 64 and y = 12. Notice how 64+12 = 76 and how 64 - 12 = 52.
=======================================================
The two numbers are 64 and 12.
