An animal collector just added some new turtles and penguins to his animal collection. He isn’t sure how many of each animal he has, though. If the animal collector knows that there are 13 heads and 34 feet total, how many penguins did he add to the collection?

There are 13 heads    so there is 13 animals total

 

x = turtles                     feet = 4x

13-x = penguins           feet = (2)(13-x)              summed = 34

4x +    2(13-x) = 34

2x = 8

x = 4   = turtles            13-4 = penguins = 9
