Find the value of two numbers if their sum is 12 and their diffrence is 4

If you ever have two numbers that add to something and have a difference of something else, the two numbers are always 1/2 the difference away from 1/2 the number.

Half of 12 = 6

Half of 4 = 2

6 + 2 = 8

6 - 2 = 4

This would be 4 and 8 because they are 4 numbers apart and 4+8=12 enjoy!
