Question

B={x: x+5=5} is not an empty set. Why?

Answer 1

Solve the  second equation
x+ 5=5
x=0

B= {0 : 5}

Answer 2

Answer:

it is not an empty set because the set has an element which is (0,5)

Step-by-step explanation:

the condition of a set is

B= {x: x+5=5}

if we put x as 0

the value will be 0+5= 5 ,

this satisfies the condition given in the set

so that means the contains the element inside it

therefore The set is not an empty set, Because the definition of an empty set is.

A set that does not contain any element is called an empty set or a null set. An empty set is denoted using the symbol '∅'. It is read as 'phi'. Example: Set X = {}. It is also called a void set or null set.
