Question 133497
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.
