    X + Y = 18

    X=chickens, Y=Cows

    2x + 4y = 60

    Let's try 8 and 10.

    16 + 40=56, no, 32+20=52, no. 8&10 do not work.

    Let's try 9 and 9.

    18+36=54, no. 9&9 do not work.

    Let's try 11 & 7.

    22+28=50, no. 14+44=58, no.

    Let's try 12 & 6.

    24+24=48, no. 12+48=60 YES!

    There are 12 cows and 6 chickens.
