Start with the given inequality



Divide both sides by 7 to isolate x



Divide

Answer:
So our answer is





Now let's graph the solution set


Start with the given inequality:



Set up a number line:


Now plot the point 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 as the boundary. This means we shade everything to the right of the point like this:
Graph of with the shaded region in blue
note: at the point , there is an closed circle. This means the point is included from the solution set.
