Best ResponseYou've already chosen the best response.0y=x+4, 2x+y = 46 are the two simultaneous equations that you can derive from the information. Next use your favourite method of solving them (out of elimination or substitution).

Best ResponseYou've already chosen the best response.1Okay, I'll use my favorite method: 2x + y = 46 y = x + 4 y = 46  2x y = y x + 4 = 46  2x 3x = 42 x = 42/3 x = 14 y = 18
