so the percentage= 45×100/100
=0.45%
as the instruction say=0.45%/180

=
16,700
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.
