You can
put this solution on YOUR website!Start with the given inequality:
Set up a number line:
Now plot the point x=3 on the number line
Now pick any test point you want, I'm going to choose x=0, and test the inequality
Plug in
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:

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