You go to the video store to rent 5 movies for the weekend. Movies rent for $2 and $3. You spend $13. How many $2 movies did you rent?

I'll be glad to check your answer.

I don't know how to do

number of $2 movies  x
number of $3 movies  5x
solve for x
2x + 3(5x) = 13
Why didn't you just do trial and error. There are only 5 choices. 
x=2?

Right.

thank you

You're welcome.
