Answer:

Step-by-step explanation:

Concept used:

 Sets are always denoted by capital letters of English alphabet and its elements are denoted by small letters of English alphabet enclosed in curly brackets.

Given:

A = { X : 3x =12 }

A = { X : x =4 }

A = { 4 }

Difference between A = { 4 } and A=4:

A = { 4 }

It means that the set A contains only one element, namely 4

A = 4

It means that the variable A assumes the value 4. It does not imply that the element 4 belongs to A.
