You can put this solution on YOUR website! there are 10 animals in one cage. Including rabbits and chickens. If there are 28 feet in the cage, How many chickens and rabbits are there in the cage?
-------
Equations:
r + c = 10
4r+2c = 28
---------------
Multiply thru the 1st equation by 2 to get:
---
2r + 2c = 20
4r + 2c = 28
----------------
Subtract 1st from 2nd and solve for "r":
2r = 8
r = 4 (# of rabbits)
------
Since r+c = 10, c = 6 (# of chickens)
