Question

How do you write ‘5 less than 4 times a number’

Answer 1

In this word problem we need to start by defining what is 4 times a number. If we call that number "x", four times that number is:

`4x`

And then, since we need 5 less than 4 times a number, we substract 5 from the previous expression:

`4x-5`

Anwer: 4x-5
