Answer 1

Answer:

no

Step-by-step explanation:

A={x:x is a natural number and 3x-1=5}

3x-1=5

3x=5+1

3x=6

x=2

A={x: 2 , x is a natural number }

So A is not a null set.

Answer 2

Answer:

No it's not not an example of empty set

put x = 2 we get,

3(2) - 1

6 - 1

5

A= { 2}

There is 1 element in the set.
