Answer 2

There are 4 human and 15 cows.

Step-by-step explanation:

Consider the provided information.

Let x represents the number of human and y represents the number of cows.

There are 19 heads.

$x+y=19$

$x=19-y$

A cow has 4 legs and human has 2 lags. The total number of legs are 68.

$2x+4y=68$

Substitute the value of x in above.

$2(19-y)+4y=68$

$19-y+2y=34$

$y=15$

Substitute the value of y in $x=19-y$

$x=19-15$

$x=4$

Hence, there are 4 human and 15 cows.
