Inequalities can be solved similarly to equations. The only difference is that if we multiply or divide both sides by a negative number we have to flip the inequality sign. Here we can solve the inequality by subtracting from both sides, so the inequality sign remains the same. Thus, the solution set is meaning all -values greater than
The endpoint is not included in the solutions set since the inequality has the symbol Therefore, it's marked with an open circle.
Now, the solution set is all -values greater than That means all -values to the right of the endpoint.
