How many legs do goats and chickens have?
First each animal has only one head. G + C = 50. That is goats plus chickens is 50 animals. Second, Goats have 4 legs and chickens have two. 4*G + 2*C = 140. That will account for all the legs. Note the constant in the first equation is in terms of animals and the constant in the second is in terms of legs. These are the units.
