No. In post #31 you've performed an illegal operation by multiplying Z1Z3Z2 by zero and ending up with Z1Z3Z2 on the left hand side.
Anything multiplied by zero is zero. So you clear the denominator away by multiplying both sides by it. Poof! it vanishes and you're left with just the numerator to deal with.
