Start with the given inequality:

x%3E3

Set up a number line:
number_line%28500%2C-7%2C13%29

Now plot the point x=3 on the number line


number_line%28500%2C-7%2C13%2C+3%29


Now pick any test point you want, I'm going to choose x=0, and test the inequality x%3E3


0%3E3 Plug in x=0


Since this inequality is not true, we simply shade the entire portion that does not contain the point x=0 using the point x=3 as the boundary. This means we shade everything to the right of the point x=3 like this:

note: at the point x=3, there is an open circle. This means the point x=3 is excluded from the solution set.
