The difference between two numbers is 14 and their sum is 8. What are the two numbers?
If the numbers' sum is 8, they can be...
1 and 7
2 and 6
3 and 5
4 and 4
I assume we are going to the negatives, though, there is no number that has a difference of 14 here.
-3 and 11 have a difference of 14 and a sum of 8, therefore...
The two numbers you are looking for are...
-3 and 11
