Question

One less than a number, which is then divided by 5, is -7. What is the number?

Answer 1

- 34

Explanation:

Let the required number be x

Therefore, one less than a number = x - 1

`(x - 1) / 5 = - 7 \\ \\ (x - 1)/(5) = - 7 \\ \\ x - 1 = - 7 * 5 \\ \\ x - 1 = - 35 \\ \\ x = 1 - 35 \\ \\ x = - 34`

Answer 2

Work backwords.

-7*5=-35

-35-1=-36.
