does that mean , in the end, that 0 = x ? 
how can nothing be anything when nothing is nothing?  |
However funny, you can't do math like that on divisions with zero.
Another example:
____________________
(Note: Using "aa" as notation for "a squared")
Given that
a = 1 and
b = 1
a = b (we now multiply with b on both sides...)
ab = bb (subtract aa on both sides...)
ab - aa = bb - aa ( put a 'outside' on left side...)
a(b-a) = bb - aa ( Use the rule for
Product of Sum and Difference...)
a(b-a) = (b + a) * (b - a) (Divide by b - a on both sides...)
a = b + a (insert values)
1 = 2
QED.
