Best ResponseYou've already chosen the best response.05x + 2y = 7 x3 > 15x+6y = 21 7x  3y = 11 x2 > 14x6y=22 you got x, then search for y

Best ResponseYou've already chosen the best response.05(1/29) + 2y = 7 2y = 7  (5/29) So. y = [7(5/9)] / 2

Best ResponseYou've already chosen the best response.05(1/29) + 2y = 7 2y = 7  (5/29) So. y = [7(5/9)] / 2 > = 3.59

Best ResponseYou've already chosen the best response.05(1/29) + 2y = 7 > 5/29 +2y=7 2y = 7  (5/29) 2y = (2035)/29 2y = 208/29 y = 208/29 * 1/2 y = 104/29

Best ResponseYou've already chosen the best response.0ok, but im still confused i am really really bad when it comes to this type of math it helps me to make notes how did you get the 203? i need explanations for every answer except the obvious ones

Best ResponseYou've already chosen the best response.0okay I will walk you through it: So we have x= 1/29 now you know how we got that so plug 1/29 into 5x + 2y = 7 This becomes 5(1/29) + 2y = 7 > 5(1/29) = 5/29 So, subtract 5/29 from both sides: 2y = 7  (5/29) Evaluate that Then divide by 2: Then y = [7(5/29)] / 2 and y = 3.59 So x = 1/29 and y = 3.59

Best ResponseYou've already chosen the best response.0the solution is (1/29,104/29)

anonymous
