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

Oct 27, 2016

$\left(4 \left(n - 5\right)\right) - 7$

#### 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:
$4 \left(n - 5\right)$

7 less than this wold be:
$\left(4 \left(n - 5\right)\right) - 7$
