    We don't do your homework for you if you don't even try first...

    Here are the rules for homework

    https://www.askmehelpdesk.com/other-...-b-u-font.html

    How do YOU think its done and what the answer should be... THEN we will help you if its wrong.

    You won't learn anything if someone else does it for you. Then you will fail a test down the road.

    smoothy is right. You should at least try.

    How about first multiplying the second equation by 2 throughout?
