Answer:

5x-2x

Explanation:

Let's call that number
.

when we are asked for a difference we must substract quantities.

In this case we need the difference between five times a number (the number is represented by
) and twice that number:

five times the number x is equal to

x+x+x+x+x=5x

twice that number x is equal to:

x+x=2x

thus, the difference is:
5x-2x
