Best ResponseYou've already chosen the best response.05x + y = 5 multiply by 2 4x + 2y = 2  10x  2y = 10 (result of multiplying by 2) 4x + 2y = 2 add 6x = 12  divide by 6 on both sides x = 2 now sub 2 in for x in one of the original equations and find y. questions ?

Best ResponseYou've already chosen the best response.05x + y = 5 5(2) + y = 5 10 + y = 5 y = 5 + 10 y = 5 check... 4x + 2y = 2 4(2) + 2(5) = 2 8 + 10 = 2 2 = 2 (correct) so x = 2 and y = 5

Best ResponseYou've already chosen the best response.0someone told me 2,5 wasnt the right answer..

Best ResponseYou've already chosen the best response.0plug it into the original equations to check... 4x + 2y = 2 5x + y = 5 4(2) + 2(5) = 2 5(2) + 5 = 5 8 + 10 = 2 10 + 5 = 5 2 = 2 (correct) 5 = 5 (correct) (2,5) is the solution because it checks out in both equations as correct
