**Quidditch**, Monday, October 8, 2007 at 12:36pmLet x=number of pigs

Let y=number of chickens

There are two equations with these two unknowns. Assume that the animals have the normal number of heads and feet for their species.

Number of heads:

x + y = 27

Number of feet:

4 * x + 2 * y = 78

Sove this equation set for x and y.

Hint:

Multiply the top equation by 2 and subtract it from the bottom to get rid of y. Sove for x. Substitute the x value into the first equation to find the y value.
