5 less than the sum of 4 times a number and 7.

Answer 1

(4n +7) - 5

The "5 less than" appearing at the beginning of the expression is confusing. In order to find 5 less than 'something,' you first must know what 'something' is - in this case it is the sum (means you're going to add) of 4 times a number, or n, and 7.
