What will be the answer for {6,8,1020} instersect {1,3,5,7}

intersection is { } or ∅

Step-by-step explanation:

A ∩ B, is the set containing all elements of A that also belong to B.

Here first set { 6, 8 , 10, . . . 20} Set of even number from 6 to 20

Second set { 1, 3 , 5 , 7} Set of odd numbers from 1 to 7

There is no common elements in the set.

Therefore intersection of the set is empty or null set.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
