Write an algebraic equation for the
following and evaluate. Tell what
the variable represents.
Sam had fish in his fish tank. 6 of
them died. There were 12 left
swimming in the tank.

originally?
Sam had fish in his fish tank. 6 of them
died. There were 12 left swimming in
the tank.
How many fish did Sam have originally?
f – 6 = 12
f = 18
f is the number of fish Sam had
originally in his tank.
