Ok...

let x = the number

You know that "the sum of 5 times the number and two times the number is 161"

Your equation is correct:

5x + 2x = 161

Are you saying that you don't know how to solve this equation?

We need to know where you are stuck. If solving 5x + 2x = 161 is a mystery, you probably need to talk to your teacher and ask for some extra help.

Are you saying you can't solve 5x + 2x = 161 for x?Storm2529 said:They want you to find what the problem is and what x is and then check it.

OK: if 5 videogames + 2 videogames cost $161, and all videogames cost the same,

how much does 1 videogame cost? Can you tell us that?

C'mon Stormy; ok: if 7 videogames cost $161, how much does 1 videogame cost?Storm2529 said:No, they want you to combine like terms and then solve for x. I know now what the next step is.

5x + 2x = 161

7x=161

That is all I have so far.
