Best ResponseYou've already chosen the best response.0Then I did 2 and 3rd equations: 3x+5yz=15 3x+5yz=15 2x+y+4z=14 10x5y20z=70 _________________ ____________________ 13x21z=55

Best ResponseYou've already chosen the best response.0now use the two equations that you got 2x+7z=12 13x21z=55 to solve for one of the variables (x or z) and go on and solve each variable one by one

Best ResponseYou've already chosen the best response.0Then I need to take my answers from the first and second and add them together. 2x+7z=12 6x+21=12 13x21z=55 13x21z=55 _________________ Then I get lost?
