Question

One number is inverse of the other. Their difference is 6. Find the number.

Answer 1

Answer:

Let one number be x and the other y. So x + y = 15

and x - y = 3 __________

adding these together makes 2x = 18

dividing both sides by 2 we get x = 9

finally x + y = 15 or 9 + y = 15 so y = 6

You should be able to plug the numbers back in to both equations and have it work.

9 and 6 do add up to 15 and their difference is 3.
