An alligator has a head 6 inches long. The tail is equal to twice the size of the head plus one half of the size of the body. The body is the size of the head plus the tail.
How long is the alligator?

Three parts - head, body, tail.
h = 6
t = 12 + b/2
b = 6 + (12 + b/2)
b = 18 + b/2
b/2 = 18
b = 36
t = 12 + 36/2 = 12 + 18 = 30
6 + 30 + 36 = 72 inches, or 6 feet
The alligator is 6 feet (72 inches) long.

let x=head=6,
y=body,
z=tail.
y=x+z
z=2x+y/2
y=6+z
z=12+(6+z)/2
2z=24+6+z
z=30
y=36
therefore size is 30+36+6=72
