Answer 2

Answer:

$5x-2x$

Step-by-step explanation:

Let's call that number $x$.

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 $x$) 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: $5x-2x$
