Take P to be the number of pigs and C to be the number of chickens. Because both anamals have a head, the sum of C and P is 143, or
C + P = 143
Because a chicken contributes 2 legs and a pig contributes 4, C times 2 plus P times 4 equals the total number of legs, or
2C + 4P = 478
divide this equation by 2 to get
C +2P = 239
Subtract the first equation from this one
P = 96
plug this into the first equation
C + 96 = 143
C = 47
96 Pigs and 47 chickens

A farmer counts 70 heads and 200 legs how many chickens and pigs does he have?
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.

I count 24 heads and 80 legs. How many pigs and how many chickens are out there?
Heads: P + C = 24C = 24 - PLegs: 4P + 2C = 80Substitute, from heads: 4P + 2 (24 - P) = 804P + 48 - 2P = 802P = 32P = 16C = 24-P = 8====================Check:P + C = 16 + 8 = 244P + 2C = 4(16) + 2(8) = 64 + 16 = 80 yay!
If A collection of chickens and pigs has a total of 70 legs and 26 heads How many chickens are there?
C+P=26 2C+4P=70 Therefore C=26-P Therefore 2(26-P)+4P=70 Therefore 52-2P+4P=70 Therefore 52+2P=70 Therefore 2P=18 Therefore P=9 Therefore C+9=26 Therefore C=17 There are 17 chickens.
There are 13 animals in the barn Some are chickens and others are pigs There are 40 legs in all How many of each animal are there?
2c + 4p = 40 c + p = 13 so 2c + 2p = 26 so 2p =14 p = 7, c = 6 Check: 7 pigs = 28 legs, 6 chickens = 12 legs, total 40 legs. QED

There are only pigs and chickens on a farm there are only 22 heads and 72 feet in all. how many pigs and chickens are there?
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)
How many pigs and chickens are there if there are 48 heads and 124 feet?
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!
2 monkeys 4 pigs 3 chickens how many legs?
2 monkeys = 4 legs3 chickens = 6 legs4 pigs = 16 legsTotal legs = 26
Two monkeys 2 pigs and 3 chickens have how many legs?
2 monkeys = 4 legs2 pigs = 8 legs3 chickens = 6 legsTotal = 18 legs
If you have 2 monkeys 4 pigs 3 chickens how many legs are there?
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.
