    Step-by-step explanation:

    Let the number of cows be x and their legs be 4x.

    Let the number of chicken be y and their legs be 2x.

    Total number of legs = 4x + 2y.

    Total number of heads = x + y.

    The number of legs was 14 more than twice the number of heads.

    Therefore, 2 × (x + y) + 14 = 4x + 2y.

    or, 2x + 2y + 14 = 4x + 2y.

    or, 2x + 14 = 4x [subtracting 2y from both sides].

    or, 14 = 4x – 2x [subtracting 2x from both sides].

    or, 14 = 2x.

    or, x = 7 [dividing by 2 on both sides].

    Therefore, the number of cows = 7.
