SOLUTION: A farm has 60 cows, pigs, and horses. There are 4 times as many cows and pigs as horses. How many horses are there?

You can put this solution on YOUR website!
ok
this is what you do
you have 60 animals total
so you have this function
60=c+p+h
then, there are four times as many cow/pigs as there are horses
so 4h=c+p
so use that in the function.
60=4h+h
i just replaced the cows and pigs with the equal in horses
so 60=5h
divide both sides by 5
and you have 12 horses.
