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.
