Question

The sum of 3 less than 5 times a number and and the number increased by 9 is 24. What is the number?

Answer 1

The number is 3

Explanation:

Let `x` be the unknown number

"3 less than 5 times a number" --> `5x-3`

"number increased by 9" --> `x+9`

The sum of 24
`5x-3+x+9=24`
`6x+6=24`
`6x=18`
`x=3`

Therefore, the number is 3
