Learn how to solve a multi step inequality with parenthesis on both sides

The video tutorial covers solving equations and inequalities, starting with single-step equations and progressing to multi-step equations. It explains that inequalities are similar to equations but require special attention to certain rules, such as when multiplying or dividing by negative numbers. The tutorial demonstrates solving a multi-step inequality, emphasizing the importance of simplifying both sides and ensuring the variable is positive. It concludes with graphing the solution set and understanding open intervals.

What does it mean when an inequality has infinite solutions, and how can this be represented on a number line?

How do you determine whether to use an open or closed circle when graphing the solution set of an inequality?
