If all were ducks there would be ony 36 legs. The extra 14 legs must represent 7 horses, which with 11 ducks would have 7 x 4 + 11 x 2 ie 28 + 22 ie 50 legs as stated.
That would be 20 legs in total.
12
13 pigs and 1 duck.
If all were horses there would be 428 legs. The shortfall of 36 legs represents 18 chickens so there are 89 horses.

Two ducks would have two legs each, or four legs in total.
Two ducks and two dogs have a total of how many legs?
Ducks have 2 legs.
That would be 20 legs in total.
the answer is ..................8
12
13 pigs and 1 duck.
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)
ducks have 2 legs ducks have 2 legs

The answer is 20 if you add all the legs up. 2 ducks = 4 legs 2 dogs = 8 legs 2 cats = 8 legs 4+8+8=20
2 ducks=4 legs 2 dogs=8 legs 2 cats=8 legs 8+8+4=18(true)
