Ok I've given this more though, and I think you haven't actually proved that 1 = 2, you have "proved" that a = 2a. You can't just substitute whatever you want into a. You need to solve for a, and you end up with a=0 and hence b=0. Since you are assuming b > 0, then your proof is contradictory so either your assumptions were incorrect or your logic is incorrect.
