Question

1) Decide whether set C and D are equal sets. Give reasons for your answer.
C = Set of even prime number.
D = y / 7y – 1 = 13

Answer 1

Answer:

Calculation of Sets

Step-by-step explanation:

Given:

C = Set of even prime number

D = y / 7y – 1 = 13

To find:

Whether set C and D are equal sets and reasons for that.

Solution:

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.

C = Even Prime Numbers = {2}

D = {y / 7x – 1 = 13}

⇒ 7x – 1 = 13

⇒ 7x = 13 + 1 = 14

⇒ y = 14/7

∴ y = 2

∴ A = B

Ans = Set A and set B are equal sets
