Best ResponseYou've already chosen the best response.0No I have not. At least I don't believe so. I know I need to reduce the problem down to like 2 equations

Best ResponseYou've already chosen the best response.0multiply eq 2 with 2 and subtract eq 1 and 2 2x+3y+z=3 2x2y+4z=28  5y3z=31(on subtraction)

Best ResponseYou've already chosen the best response.0similarly multiplying eq 2 by 3 and subtracting 2 and 3

Best ResponseYou've already chosen the best response.0I don't know, its just still very confusing to me. So can you go back to the beginning..... I have 2x + 3y + z = 3 but where did the equation blow it come from?
