Answer:

  • 15 hippos
  • 27 birds

Step-by-step explanation:

You have a total of 114 legs among hippos and birds, of which there are a total of 42. You want the number of each kind of animal.

Setup

Let h represent the number of hippos. Then 42-h is the number of birds, and the total number of legs is ...

  4h +2(42 -h) = 114

Solution

Simplifying the equation gives ...

  2h +84 = 114

  2h = 30 . . . . . . subtract 84

  h = 15 . . . . . . . . number of hippos

  42 -h = 27 . . . . number of birds

There were 15 hippos and 27 birds.
