Question

One number exceeds the other by 9 and their sum is 81. Find the
numbers.

Answer 1

36, 45

Explanation:

Using equations you get
`x + x+9=81` because one number is 9 more than the other and the sum is 81. Simplifying you get,
`2x = 72`. Divide both sides by 2 to get
`x=36`. Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.
