good grief, here....
if its horses and 3 legged cows....
take number of heads X 4(amount of horses legs)... take that result and minus the number of legs on the farm.
Now take that number and subtract it from the amount of heads on the farm. The number you got from first subtraction is the number of 3 legged cows, so if thats what you need, you dont have to subtract the second time.
If its 3 legged cows and chickens, the math is done the same except you multiply amount of cows legs(3) instead of horses(4).
if its horses and chickens, the only thing different is after you subtract the legs from your multiplied number, divide it by 2 and you get the number of chickens on the farm, for the number of horses, simply subtract the number of chickens from the number of heads. Easy as pie, simple math, quicker than all that other mumbo jumbo.
