Olenka [21]

Answer:

He have <u>47</u> ducks and <u>7</u> cows.

Step-by-step explanation:

Given:

Farmer Jones raises ducks and cows.

He looks out his window and sees 54 animals with a total of 122 feet.

Now, to find the each type of animal he have.

Let the number of ducks be x.

And the number of cows be y.

So, total number of animals are:

x+y=54

x=54-y  ....( 1 )

As, the feet of cows are 4 and ducks are 2.

Now, the total number of feet are:

2(x)+4(y)=122

2x+4y=122

Substituting the value of x from equation (1) we get:

2(54-y)+4y=122

108-2y+4y=122

108+2y=122

<em>Subtracting both sides by 108 we get:</em>

2y=14

<em>Dividing both sides by 2 we get:</em>

y=7.

<em>The number of cows = 7.</em>

Now, to get the number of ducks we substitute the value of y in equation (1):

x=54-y\\x=54-7\\x=47.

<em>The number of ducks = 47.</em>

Therefore, he have 47 ducks and 7 cows.
