Farmer Fran has 38 barnyard animals consisting of only chickens and goats. If these animals have 116 legs how many of each type
musickatia [10]

Answer: There are 20 goats and 18 chikens.

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

If the number of chickens is represented by C, and the number of goats is G.

Total of Animals equation:

a)C+ G = 38

Total of legs equation (since chickens have 2 legs and goats have 4 ):

b)2C + 4 G =116

If we multiply a) by 2 and subtract a) from b).

<em>2C + 4 G =116 </em>

<em>- </em>

<em>2C + 2 G =76 </em>

<em>_________ </em>

<em>2G = 40 </em>

  • Solving for G:

G = 40/2

G= 20

Replacing the value of G on any equation:

a) C+ (20) =38

  • Solving for C

C =38-20

C=18

There are 20 goats and 18 chickens.
