Hello! I need some help figuring out what I did wrong here. I understand for the most part but I messed up somewhere. Work would be nice so I can visually see the right process!! ​

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)
