Solve each system by the addition method.

3x - 4y = 7
2x - y = 3

Put your answer in ordered pair (x, y) form.

Could really use the help. I don't have anyone to help me with this.

Where is your work? Given the help you already received in the other thread, you should be able to at least attempt this question.

I don't understand how to do it . I'm sorry it's confusing.

And we understand that, but if you don't at least show us you're making an attempt to learn the material, it's not very likely you'll get many responses. We usually consider solutions without any work shown as doing homework for the student which is not something we're willing to do. We're glad to help, but you should show some of your own attempts or thoughts on the problem first.
