There are a total of 10 pigs and ducks in the barn. There are 36 legs in all (each p*g has four legs and each duck has two legs). Use substitution to solve the linear system of equations and determine how many pigs, x and ducks, y there are. Express the solution as an ordered pair (x,y).​

4 x  +  2 y    = 36 

x+ y = 10        or  y = 10-x     sub this into firs equation

 

4x + 2 (10-x) = 36

2x + 20 = 36

x = 8     pigs              8+ y = 10     y = 2 ducks
