This means we are looking for the intersection of the Physics and Mathematics circles, which includes:
The students who registered for only Mathematics and Physics (4x).
The students who registered for all three subjects (2x)
So, the total number of students who registered for Physics and Mathematics is: 4x+2x=6x
