Which law relates to the ideal gas law?

Ideal Gas Law ::

The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas:

$\frac{P1V1}{T1} = \frac{P2V2}{T2}$

Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.
