Question 204235
the fish has a head 9 inches long
 The tail is equal to the size of the head plus one-half the size of the body
 The body is the size of the head plus the tail
 how long is the fish?
:
Let x = length of the fish:
:
length of fish = head + tail
x = 9 + (9+.5x)
x = 18 + .5x
x - .5x = 18
.5x = 18
x = {{{18/.5}}}
x = 36"
