3x+8y=1

7x+4y=17,

after multiplying the top equation by seven and the bottom one by three to get

21x+56y=7

21x+12y=51

subtraction rather than addition is used, being that the two twenty-ones share the same sign, right?

Is (3,-1) the correct answer for this problem?

I'm sorry for bombarding you with so many questions and such inconvenience, but I'd greatly appreciate it if I received an accurate reply to my inquiries by tomorrow night. The earlier the better, but don't stress on it too much. It's just that I have to take my math final on Thursday =( Therefore, it would be highly appreciated to have an answer as soon as possible =) Well, thanks for your cooperation. I'm looking forward to hearing from you!
