Answer:
[tex]5x-2x[/tex]
Step-by-step explanation:
Let's call that number [tex]x[/tex].
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 [tex]x[/tex]) and twice that number:
five times the number x is equal to
[tex]x+x+x+x+x=5x[/tex]
twice that number x is equal to:
[tex]x+x=2x[/tex]
thus, the difference is: [tex]5x-2x[/tex]
