Best ResponseYou've already chosen the best response.1For example if you had 4a + 2b = 15 2a + 2b = 7 you would need to get the B's to equal zero in this case

Best ResponseYou've already chosen the best response.1so you would (2a + 2b = 7) *1 and it would be this: 2a  2b = 7

Best ResponseYou've already chosen the best response.1the B's now cancel out. 4a  2a = 6a = 8 < 15  7 = 8

Best ResponseYou've already chosen the best response.1the answer would actually be 2a 4a + 2a = 2a = 22< 15 + 7 = 22. 2a = 22 then divide 2 from both sides to get A = 11. Then insert 11 into both equations and solve to get y
