    Answer:

    4 pigs and 8 chickens.

    Step-by-step explanation:

    Let number of chickens be c and number of pigs be p:

    Animals:

    c + p = 12

    Legs:

    2c + 4p = 32

    Multiply the first equation by 2:

    2c + 2p = 24

    Subtract this from the second equation:

    2c – 2c + 4p – 2p = 32 – 24

    2p = 8

    p = 4

    and therefore c = 12 – 4 = 8.
