Question

The sum of two numbers is 45. The first is 9 less than the second. How do you find the numbers?

Answer 1

18 and 27

Explanation:

Lets call our first number `x`. This means the second number is `x+9`
Adding them together gives

`x + (x+9) = 45`

`2x+9 = 45`

`2x = 36`

`x = 18`

`implies x+9 = 27`
