Armani, rather than have a tutor do your homework for you. Look at the full explanation that I provided for a similar problem that you submitted. Then you will be able to solve this problem for yourself.

By the way, I'll give you a hint. Multiply the first equation by (–2) and then add the new version of the first equation to the second equation, so that the x terms drop out.

I agree. Armani give yourself a chance to conquer these types of problems by using one example to tackle the others. You will surprise yourself :)
