Question

If n represents a number, then how do you write an expression for 7 less than four times the difference of n and 5?

Answer 1

`(4(n-5)) - 7`

Explanation:

First you need to get the expression for the difference of `n` and 5 which is:
`n - 5`.

Then four times this would be:
`4(n - 5)`

7 less than this wold be:
`(4(n-5)) - 7`
