Answer 3

A farm raises a total of 220 chickens and pigs.The number of legs of the stock in the farm totals 520 .How many chickens and pigs are at the farm?

Answer 4

Number of animals is 220 given.
Let p = pigs
Let c = chickens. Then c + p =220 Now we do the legs. Here is a fundamental fact, chickens have two legs and pigs have 4 legs. We now can write:
2c + 4p = 520
Substitute for c, in that c=220-p
2(220-p) + 4p = 520
440 -2p +4p = 520
2p =520 -440
2p = 80
p = 40 forty pigs
c = 180 chickens
