Question

Nine less than a number is -24. How do you find the number?

Answer 1

`-15`

Explanation:

Let the number be `x`. The phrase Nine less than a number suggests that `9` has been subtracted from the number. So, we can write it as `x-9`. Then, it also states that the result will be `-24`.

So, we get:

`x-9=-24`

`x=-24+9`

`=-15`

Therefore, the number is `-15`.
