P1V1/T1 = P2V2/T2
If you double so P2 = twice and you duoble T so that T2 becomes twice see what happens in the equation. You will have
P1V1/T1 = 2*P2V2/2*T2 and you see that the 2 in the numerator cancels with the 2 in the denominator so you have the ORIGINAL EQUATION so V2 doesn't change. You can do it another way.
Let P1 = 1, V1 = 1, T1 = 273 . Now make P2 = 2, V2 = ? and T2 = 546 ans solve for V2 = ?
V2 = P1V1T2/P2T1 and substituting
V2 = 1*1*546/2*273 = which reduces to 1*1*2/2*1 or 1 so V didn't change when you doubled P and doubled T
