Best ResponseYou've already chosen the best response.1Ok so theres 40 peawingspans and 40 deer, so deer have 4 legs, so 40 times 4 = 160 then the peawingspans have 2 legs and there are 40 of them so 20 so then there is ur other 40 u were missing so the answer would be 40. but where did i go wrong @waterineyes

Best ResponseYou've already chosen the best response.0Just system of linear equations: x : deer and y : peawingspan.. x + y = 80 4x + 2y = 200 So: 4x + 4y = 320 4x + 2y = 200 2y = 120 y = 60..
