Question

(c) E = {x : x ∈ W, 3x + 1 = 2} is an empty set or not?

Answer 1

Answer:

no

Step-by-step explanation:

E= 0 so it is not an empty set

Answer 2

Answer:

Yes, it is an empty set

Step-by-step explanation:

1. Any number multiplied with 3 is equal to (or) greater than
2. Except zero because any number multiplied with 0 is equal to zero

• According to the given condition it should be equal to 2

Trial and error:

If (x=0)

• 3(0)+1 =1 which is not equal to 2

If (X=1)

• 3(1)+1=4

{Hence it is an empty set}
