Answer:

  • 30 ducks
  • 8 pigs

Step-by-step explanation:

Let p represent the number of pigs. Then the number of ducks is 38-p and the number of legs is ...

  4p +2(38 -p) = 92

  2p = 16 . . . . . . . . . . . . collect terms, subtract 76

  p = 8 . . . . . . 8 pigs in the field

  38-p = 30 . . . number of ducks in the field

There are 30 ducks and 8 pigs in the field.
