Question

The sum of two whole numbers is 64 and their difference is 20. What is the bigger number?​

Answer 1

42 and 22 are the numbers

Explanation:

Let the numbers be x and y

`x + y = 64`

`x - y = 20`

On adding both

`x + y + x - y = 64 + 20`

`2x = 84`

`x = (84)/(2)`

`x = 42`

Using 1

`42 + y = 64`

`y = 64 - 42`

`y = 22`
