Answer: There are 4 cows and 9 ducks

Step-by-step explanation:

The first thing you would want to do is realize that cows have four legs and ducks have two. Secondly, you want to guess and check. So my answer is 4 cows and 9 ducks. This can also be proved because four cows times the cow's four legs is sixteen. And nine times the chickens's two legs is eighteen. So if you add 18+16 you get 34.
