Question

what is the difference between union set and universal set

Answer 1

According to the Question :

⇒ \dfrac{x \: + \: 1}{x \: + \: 3} \: = \: \dfrac{2}{3}

x+3

x+1

=

3

2

⇒ 3 (x + 1) = 2 (x + 3)

⇒ 3x + 3 = 2x + 6

⇒ 3x - 2x = 6 - 3

⇒ x = 3

The numerator of fraction = 3

• The denominator of a fraction = x + 2

⇒ 3 + 2

⇒ 5

The denominator of a fraction = 5

Fraction = \dfrac{3}{5}

5

3

Step-by-step explanation:

The universal set is a set which consists of all the elements or objects, including its own elements. It is represented by just a symbol 'U'. But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both.
