Two numbers total 50 and have a difference of 28. Find the two numbers.

Two numbers total 50 and have a difference of 28. Find the two numbers.

Using x and y as our two numbers, we write the following 2 equations:

1. x + y = 50
2. x - y = 28

Add the 2 rows:
2x = 78

Divide each side by 2:
x = 39

If x = 39, then from (1), we have
y = 50 - 39
y = 11
