Answer:

21 pieces of chickens.

Step-by-step explanation:

Given:

The farmer has a total of 40 animals. ( cows and chicken )

He counts the legs of all his animals and realizes he has a total of 118 legs.

Question asked:

How many chickens does the farmer have ?

Solution:

Let number of chickens = x

Then  number of cows = 40-x

Now, as here given that total number of legs are 118 of all the animals, and as we know that a chicken has two legs and cow has four legs, hence the equation will be :

<u>Total number of legs = Number of legs having chickens + Number of legs having cows</u>

118 = 2x+4(40-x)\\118=2x+160-4x

118=-2x+160

Subtracting both sides by 160

-42=-2x

By adding both sides by minus

42 = 2x\\

By dividing both sides by 2

x =21

Hence, farmer have 21 pieces of chickens.
