Arrange the given steps in the correct order to find A and B if A and B are two sets where A B = {1, 5, 7, 8}, B A = {2, 10} and A union B = {3, 6, 9}

A= (A-B) union (A intersection B) B= (B-A) union (A intersection B)

A= {1, 3, 5, 6, 7, 8, 9}

B= {2, 3, 6, 9, 10}

A= {1, 5, 7, 8} union {3, 6, 9}

B= {2, 10} union {3, 6, 9}
