You can solve using...
elimination (very tedious)
Gauss-Jordan (tedious, and prone to simple arithmetic errors)
Cramer's rule (straightforward, but with complicated arithmetic)
graphing calculator, or any other tool that solves systems of equations (by far the easiest)

But you don't learn anything by having us do the work for you.

If you have a specific question about a particular method for solving the system of equations, re-post, asking that specific question.

But if you're just wanting us to do your work for you, then don't bother to re-post; the tutors here are only interested in helping YOU learn how to do the work.
