Can someone me with this algebra question 100% correct only

First, let's start with the part that says twice a number. If the number is n, then twice a number would be 2n. Then if we want to write out six less than two times a number, it would be six less than 2n or 2n-6 so the second choice.

Hope this helps

Six less than twice a number is 2n-6. hope this will help you .
