Aclown has 21 animals that he uses in his magic show. some of the animals are birds, the rest are bunnies. the animals have a total of 76 legs. how many of each animal does he have?

The answer to your question is:

bunnies = 17 bunnies

birds = 4 birds

Step-by-step explanation:

Data

animals = 21

birds = b = ?

bunnies = u = ?

total legs = 76

Process

                                 b + u = 21               (1)

                                2b + 4u = 76           (2)

Solve by elimination

                              -2b - 2u = -42

                               2b + 4u = 76

                                       2u = 34

                                         u = 17 bunnies

                                b + 17 = 21

                                b = 21 - 17

                                b = 4 birds
