There are 18 animals in the farm. Some ar chickens and some are cows. I counted 50 legs in all. How many of the animals are cows and how many are chickens?

K+C=18
2K+4C=50

Can someone help me to solve this problem. Thank you.

  1. you can easily see that K = 18-C
    So, put that into the 2nd equation and you have

    2(18-C)+4C = 50
    36-2C+4C = 50
    2C = 14
    C = 7
    So, K = 11
