Question

Decide whether set A and B are equal sets. Give reason for your answer.
A = Even prime numbers
B = {x|7x-1=13}

Answer 1

Answer:

set A and B are equal sets

A = B = {2}

Step-by-step explanation:

A = Even prime numbers

only even prime number is 2

so A = { 2 }

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

7x - 1 = 13

=> 7x = 14

=> x  = 2

=> B = { 2}

so A & B both are {2}

A = B = {2}

Hence  set A and B are equal sets

Answer 2

Answer:

Set A and B are equal sets.

A = B = {2}

Step-by-step explanation:

As per the question,

We have given that,

A = Even prime numbers

As we know that 2 is the only even prime number.

Therefore,

A = { 2 }

Now,

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

∴ 7x - 1 = 13

⇒ 7x = 14

⇒ x  = 2

⇒ B = { 2}

Here we can conclude that

A = B = {2}

That means set A and B are equal sets.
