1.) y=1/6x+8

-2x+12y =-11

2.)y = 5x + 6

-18x + 3y = –54

Could someone show me how to do these problems? I keep asking people t oshow me how, but none of them do. They just tell me the answer, I want to know how to do the problems step by step, because I will be taking a test with similar problems soon.
