Chickens and Cows

-

When asked how many chickens and cows he had on his farm Mr Brown refused to answer directly, but he did say that the total number of heads was 30 and the total number of legs was 100. How many of each was there?

    If the total number of heads was 30 and the total number of legs was 100, then we can make 2 equations:

    2x + 4y = 100
    x + y = 30

    Now using systems of equations we get x = 10 and y = 20
