Chickens and rabbits

In the yard were chickens and rabbits. Together they had 18 heads and 56 legs. How many chickens and how many rabbits were in the yard?

chickens:  8
rabbits:  10

Step-by-step explanation:

a+b = 18
2•a+4•b=56

a+b = 18
2a+4b = 56

a = 8
b = 10

Our linear equations calculator calculates it. Did you find an error or inaccuracy? Feel free to write us. Thank you! Math student
We know that chicken has 2 legs and rabbit has 4. Assume that all heads are of chicken = 44*2 = 88. Now the difference between the total no. Of legs = 124-88 = 36. 36/2 =18 legs of Rabbits and 44-18 = 26 for chicken

40 chickens means 80 legs rest 10 legs .rabbit has 4 legs or 2 legs?10 legs will be shared among rabbit.

A:  There are:
a = 27 chicken
b = 29 rabbit

Do you have a linear equation or system of equations and looking for its solution? Or do you have a quadratic equation?
