Best ResponseYou've already chosen the best response.1i would just use elimination after dividing the second equation by 2.

Best ResponseYou've already chosen the best response.1or, you can divide the second equation by 2 and then tell me what clue do you have (it's ok if you don't come up with any thoughts).

Best ResponseYou've already chosen the best response.1Do you have to (like just must) to use matrix to solve it?

Best ResponseYou've already chosen the best response.0I think its inconsistent because it can't be A. or B.

Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle 2x + 4y = 16 \\ 4x – 8y = 32 }\) divide the second equation by 2 and rewrite the system of equations for me please.

Best ResponseYou've already chosen the best response.0If I graph the equations they never cross so it would be inconsistent, right?

Best ResponseYou've already chosen the best response.1but you should obtain that result not by graphing
