  1. since each animal only has one head, there must have been 40 animals
    let the number of cows be x
    then the number of chickes is 40-x

    4x + 2(40-x) = 112
    4x + 80 - 2x = 112
    2x = 32
    x = 16

    so 16 cows and 24 chickens

  5. X=cow
    Y=chicken
    X+y=35
    Y=35-X
    4x+2(35-x) =96
    4x+70-2x=96
    4x-2x=96-70
    2x=26
    X=26:2
    X=13(cows)
    Chicken=35-13
    =22 chickens
