Celina,
What I would do is replace the variables with the numbers and set it up like this:
(3 x 3) + (2 x 1) 7.
What's strange is that I got 14, too. The key could be incorrect, I have had mistakes in my math book before. If this homework isn't being graded, don't stress out about it, I'm sure your teacher will understand if it's not right. Good luck!
