There are a total of 11 ducks and goats in the barn. There are 34 legs in all (each duck has two legs and each goat has four
legs).
Use substitution to solve the linear system of equations and
determine how many ducks, x, and goats, y there are. Express
the solution as an ordered pair (x, y).

Use the elimination method to solve the system of equations -x+5y=-4 and 4x+3y=16
