A long time ago there was a village.The peasants there knew there were 2 types of creatures in the village pond-frogs and chans(a 3 legged creature).There were 3600 creatures and 13000 legs in the pond.Can you figure out how many frogs and chans there were in the pond?

This is quite simple but still hard. I had to give my freind the answer because she just gave up
