Janes aquarium holds goldfish, turtles, and snails. there are 16 legs, 10 shells, and 36 eyes. how many creatures of each type are in the aquarium? (Hint: snails have one leg and one shell)
Please please help me. I figured out there are 12 pets(I think) but i can not find out anything else

36/2 = 18
Since each creature has 2 eyes each, there must be 18 pets.
10 of these pets have shells; so there must be 10 snails and turtles combined, leaving:
8 goldfish
2 turtles (2 shells and 8 legs)
8 snails (8 shells and 8 legs) 
THANK YOU SO MUCH!!

You're very welcome.
