We know that two sets A and B are said to be equal, if every element of set A is in set B and every element of set B is in set A. It is symbolically written as A = B.

A = Even Prime Numbers = {2}

B = {x| 7x – 1 = 13}

7x – 1 = 13

7x = 13 + 1 = 14

x = 14/7

x = 2

A = B

Ans. Set A and set B are equal sets.
