if there are 22 heads, then u know there are a total of 22 animals...unless of course u have a mutated one with 2 heads...lol

chickens (c) have 2 legs and rabbits (r)  have 4 legs.

c + r = 22.....c = 22 - r
2c + 4r = 76 legs

2(22 - r) + 4r = 76
44 - 2r + 4r = 76
44 + 2r = 76
2r = 76 - 44
2r = 32
r = 32/2
r = 16

c + r = 22
c + 16 = 22
c = 22 - 16
c = 6

so there is 6 chickens and 16 rabbits

There are rabbits and chickens in Sally’s backyard: 22 heads and 76 legs. Hence, there are 6 chickens and 16 rabbits.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

There are rabbits and chickens in Sally’s backyard: 22 heads and 76 legs.

We know that Chickens (c) have 2 legs and Rabbits (r) have 4 legs.

c + r = 22.....c

= 22 - r

2c + 4r = 76 legs

2(22 - r) + 4r = 76

44 - 2r + 4r = 76

44 + 2r = 76

2r = 76 - 44

2r = 32

r = 32/2

r = 16

Therefore,

c + r = 22

c + 16 = 22

c = 22 - 16

c = 6

Hence, there are 6 chickens and 16 rabbits.
