Answer:

2n-7

Step-by-step explanation:

"7 less than twice a number n"

is the same as

"7 less than (twice a number n)".

I put ( ) around that one part because I want you to focus on that part first.

Twice a number n means 2 times that number n or 2n.

So now we have

"7 less than 2n".

This means 2n-7.
