x%2B5%3E-13 Start with the given inequality



x%3E-13-5Subtract 5 from both sides


x%3E-18 Combine like terms on the right side

--------------------------------------------------------------
Answer:
So our answer is x%3E-18





Now let's graph the solution set


Start with the given inequality:

x%3E-18

Set up a number line:
number_line%28500%2C-28%2C-8%29

Now plot the point x=-18 on the number line


number_line%28500%2C-28%2C-8%2C+-18%29


Now pick any test point you want, I'm going to choose x=0, and test the inequality x%3E-18


0%3E-18 Plug in x=0


Since this inequality is true, we simply shade the entire portion in which contains the point x=0 using the point x=-18 as the boundary.This means we shade everything to the right of the point x=-18 like this:

note: at the point x=-18, there is an open circle. This means the point x=-18 is excluded from the solution set.
