Let the number of cows = x
Let the number of chickens = y
Total number of heads = x+y
Every cow has 4 legs and every chicken has 2 legs
Total number of legs = 4x+2y
Given, the number of legs was 16 more than twice the number of heads.
4x+2y = 2(x+y)+16
4x+2y = 2x+2y+16
2x = 16
x = 8
Therefore the number of cows = 8
