Best ResponseYou've already chosen the best response.0So if x=10/3  2y/3 and z =3 then we can write 5x+5y+4z=3 5(10/3  2y/3) + 5y +4(3) = 3 We can now solve for y

Best ResponseYou've already chosen the best response.0Well I just told you how you can solve for y 5(10/3  2y/3) + 5y +4(3) = 3

Best ResponseYou've already chosen the best response.0okay, I trust that you did the math and are not just taking your friends answer. So we have z= 3 and y = 1dw:1351126015670:dw
