Question

decide whether set A and B are equal sets give reason for your answer A=Even prime number B={x|7x-1=13}

Answer 1

Given: A = Even prime number and B = { x | 7x - 1 = 13 }

To find: Whether set A and B are equal?

Solution:

• Now we have given that set A is Even prime number.

• So we have only one even prime number and that is 2.

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

• Now we have B as:

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

• Taking the equation, we get:

                  7x - 1 = 13

                  7x = 14

                  x = 2

• So B has an element as 2, B = { 2 }. ...................(ii)

• So from (i) and (ii), we have:

                  A = B = {2}

Answer:

             So the set A and B are equal sets.

Answer 2

Set A is even Even prime number.

A = {2} ....(1)

Now we have B as:

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

Taking the equation,we get:

7x - 1 = 13

7x = 14

x = 2

So, B has an element as 2

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

So, from (1) and (2), we have:

A=B={2}

ANSWER:

So the set A and B are equal sets..
