40 chickens and 30 pigs
This can be solved with 2 equations. Let p = the number of pigs and c = the number of chickens. Pigs and chickens each have 1 head, so p+c=70. Pigs have 4 legs and chickens have 2, so the total number of legs is 4p+2c=200.
Solve this "system of equations" by substitution: The first equation can be written as p=70-c. Substitute the right side for p in the second equation:
4(70 - c) + 2c = 200
280 - 4c + 2c = 200
280 - 2c = 200
-2c = 200 - 280
-2c = -80
c = 40.
Substitute this back into p=70-c: p=70-40=30.
There are 40 chickens and 30 pigs.
Check (in the words of the question): 40 chicken heads and 30 pig heads = 70 heads. 40x2=80 chicken legs, and 30x4=120 pig legs; 80+120=200 legs. Check!

2 monkeys = 4 legs 4 pigs = 16 legs 3 chickens = 6 legs 26 legs total
26 all together monkeys each have 2 pigs have 4 and chickens have 2 2*2=4 4*4=163*2=6 4+16+6=26
A monkey has 4 legs, a pig has 4 legs and a chicken has 2 legs. Therefore, 2 monkeys has 8 legs. 4 pigs has 16 legs. 3 chickens has 6 legs. Total no. of legs = 8+16+6 =30 legs

35 pigs, 65 chickens
There are 5 chickens and 6 pigs in the barn. Each chicken has 2 legs and each pig has 4 legs.

Let c represent the number of chickens and p represent the number of pigs.Since chickens and pigs have one head each, 70 heads = c + p.Since chickens have 2 legs and pigs have 4 legs, 200 legs = 2c + 4p.Subtracting twice the first equation (140 = 2c + 2p) from the second, we get60 = 2porp = 30 pigsRewriting the first equation as c = 70 - p, we get c = 40 chickens.
14 pigs 8 chicken's Since there are 22 heads, let the number of pigs be x and the number of chickens be 22 - x. Since pigs have 4 legs and chickens have 2 legs, and there are 72 legs in all, we have 4x + 2(22 - x) = 72 4x + 44 - 2x = 72 2x + 44 = 72 2x + 44 - 44 = 72 - 44 2x = 28 2x/2 = 28/2 x = 14 (the number of pigs) 22 - x = 22 - 14 = 8 (the number of chickens)
Since PIgs don't fly yet, we will say they have no wings and we say chickens have 2 legs. Let C be the number of chickens and P be the number of pigs. Also, let's assume each chicken has two wings. 4P+2C=24 2C=12 so C=6 4P+12=24 4P=12 so P=3 6 chickens and 3 pigs. This answer must be changed when pigs fly!
two monkeys- 4 legs four pigs- 16 legs three chickens- 6 legs equals 26 legs
2 monkeys = 4 legs 4 pigs = 16 legs 3 chickens = 6 legs 26 legs total
14 chickens and 11 pigs.
Two monkeys = four (2 legs x 2 monkeys) Four pigs = sixteen (4 legs x 4 pigs) Three chickens = six (2 legs x 3 chickens) All together there are twenty six legs.
The 2 monkeys each have 2 legs, so a total of 4 legs. The 4 pigs each have 4 legs, so a total of 16 legs. The 3 chickens each have 2 legs, so a total of 6 legs. In total, the monkeys, pigs, and chickens have 26 legs.
