Help!
Diane counted 28 geese and horses on the farm. Altogether, there were 72 legs on all of the animals. How many were geese and how many were horses?

Re: Help!
geese = x, horses = y
[1] : x + y = 28 //number
[2] : 2x + 4y = 72 //legs
[3]=[2]/2 : x + 2y = 36
[3]-[1] : y = 8
[1] : x + 8 = 28, x = 20
geese = 20, horses = 8
