let's break this apart into manageable pieces:
a fish was caught whos tail weighs 9 pounds.
Let the Tail (T) = 9 pounds
His head weighed as much as his tail and half his body,
Head (H) = T + 1/2 Body (B)
H=9+B/2
and his body weighs as much as his head and his tail.
B=H+T
B=H+9

how much does the fish weigh
since we know that the head =9+b/2, we can substitute into our second equation:
B=9+b/2+9
B=18+b/2
b-b/2=18
b/2=18
b=36
so the body weighs 36 pounds,
the head weighs 27 pounds
and the tail weighs 9 pounds
the fish (in total) weighed 72 pounds
That is certainly a whopper!
