@starryknight:  remember, the most you can ask from others is guidance towards solving this and other problems yourself.  Kindly don't ask for "best answer" and promise a medal.  Instead, please ask questions that would help you know better what to do.
Your best choices here include the following methods:
1.  elimination by substitution
2.  elimination by addition/subtraction
3.  graphing
Which have you used before and which are you going to try this time?
