- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------

Thus:

-----------------------------------------
Number of chicken:
Since 






There are 8 chickens in the yard.
