So basically im in this homeschool called Abeka Academy, and im a little behind because of the events I had to take part of.. but my classes arent live so instead of watching my class tapes.. I went on quizlet to get the answers because the end of the semester ends tommorrow... Can anyone help me find out if x=2y+5 (2,1) is a solution , -6x + 6y+9 (1/2 , 2) is a solution and if 7x-8y=13 ( 3,1) is a solution. Please help me, its urgent i pass.!
