As we can see in the question that the value of X in the scenario of A∪B=A∪C, now as we can see that all the value of B is in A and C, therefore X is equal to both A and X
Now the question says that A∩B=A∩C
Thus we can say that both C and B have the value of A in their sets respectively, therefore, we can also say that if values of B are in C, then vice versa is also possible.
Therefore, taking both the cases we can say that the values of B are in C and vice versa,
Hence, B = C.
