Best ResponseYou've already chosen the best response.0So take the first equation and make it \[3y = x + 12\]

Best ResponseYou've already chosen the best response.0Which is \[y = \frac{ x }{ 3}  4\]

Best ResponseYou've already chosen the best response.0so then take that and plug it in to 2x + 6y = 60 \[2x + 6(1/3x−4) = 60\] and then simplify
