Graphing Inequalities when variables cancel out?

Question

Do I graph on a number line when variables cancel out in an inequality if the statement is true? And if I do, then how would I put the inequality on a number line?

 

For example, this true statement; 18>- 27

 

That is a true statement, but what would I write after that for the number line? 

Answer 1

Shade you entire number line

Answer 2

You only graph the solution of the variable, since the variable can have many possible solutions.
