Given:
Height of statue or liberty from the ground = 305 feet
Model is the actual size of the statue of liberty.
To find:
The height of the model of statue.
Solution:
According to the question,
Model = of the actual size

Let's rewrite the expression as
So, if , you may divide both sides by
, the equation becomes
, and the only solution is
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead , you are multiplying both sides by zero, so the equation becomes
So, it doesn't matter which value for x you choose, because you will always end up with , which is obviously always true.
