Question

Decide whether setA&B are equal sets give reason for your answer​ A=even prime no. B={x|7x-1=13}​

Answer 1

Step-by-step explanation:

A = Even prime numbers

B = {x | 7x - 1 = 13} =

Solution:

A = Even prime numbers %3! Since 2 is the only even prime

number,

. A = {2} ...(i)

B= {x | 7x - 1 = 13}

Here, 7x - 1 = 13

.: 7x = 14

.: x = 2

: B = {2} ...(ii)

The element in set A and B is identical.

[From (i) and (ii)] ... :: A and B are equal sets.
