(adsbygoogle = window.adsbygoogle || []).push({}); There's a flaw in my logic, and I cannot find it.

Ok, all you are allowed to use is Charles' Law (V/T = K) and Boyle's Law (PV = K) and you have to derive an equation relating pressure and temperature.

V = kT

V = k/P

kT = k/P

PT = 1

Therefore P_{1}T_{1}= P_{2}T_{2}

But, this is the exact opposite of what Gay-Lussac's Law states
