Calculate the new pressure with
P1V1 = P2V2
The pressure had to decrease if the volume increased. See Boyle's Law
please help me understand this question
If measurements of a gas are 50L and 300 kilopascals and then the gas is measured a second time and found to be 75L, describe what had to happen to the pressure (if temperature remained constant). Include which law supports this observation.

volume goes up, pressure goes up too
The pressure had to increase if the volume increased. See Charles' Law
It is stated that the temperature remained constant, therefore it's Boyle's Law, not Charles' and the pressure had to have decreased if the volume went up.
Charles law - volume/temp both increase because they are related
