Answer:
Step-by-step explanation:
Ok, so there are rabbits and chickens
Rabbits have 4 legs and 1 head
Chickens have 2 legs and 1 head
So obviously we have a total of 39 animals
Let's make rabbits = x and chickens = y
So now we can make an equation for heads and and equation for legs.
Legs:
4x + 2y = 126
Heads:
x + y = 39
Now we can use substitution to solve.
If x + y = 39, then y = 39 - x
So,
4x + 2(39-x) = 126
Distribute and Combine like terms
4x + 78 - 2x = 126
2x + 78 = 126
2x = 48
x = 24
Plug x back in to the second equation
(24) + y = 39
y = 15
That means,
x = rabbits = 24
y = chickens = 15
