Answer 1

Let the number of ducks be 'x' and number of cows be y'

A cow has four legs and a duck has two.

A cow and a duck, both have one head.

Based on the relation given in the question, we can form a linear equation in two variables.

2x + 4y = 2(x + y) + 28

x + 2y = x + y + 14

y = 14

That means there are in total 14 cows.
