Let x = ducks and y = pigs
x (ducks) + y (pigs) = 22 (total animals)
2x (legs of ducks) + 4y (legs of pigs) = 56 (total legs)
Multiply the first part (the total animals) by two
2x + 2y = 44
then subtract the two problems
2y = 12 then y = 6
go back to the original x + 6 = 22 then x = 16
16 ducks (32 legs) + 6 pigs (24 legs) = 22 animals (56 legs)
