Question

The sum of two numbers is 18. The difference of the numbers is 12. How do you find the two numbers?

Answer 1

If you call the smallest number `x`, then the larger number must be `x+12` (=difference already expressed)

Explanation:

`x+(x+12)=18->2x+12=18->2x=6->x=3`

The numbers are `3and15`
