Janice has 15 pets. Each of her pets is either a dog or a bird. If her pets have a total of 38 legs, how
many dogs and how many birds does Janice own?

Hi!

These can be set up as systems of equations.

Let b = the number of birds, and let d = the number of dogs.

b + d = 21

2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)

You can solve this using either elimination or substitution.
