All Real Numbers Solution to a Compound Inequality

The video tutorial explains how to solve and graph a compound inequality on a number line. It covers the process of graphing two inequalities, one less than or equal to 7 and the other greater than or equal to 7, using closed circles to indicate inclusion. The tutorial emphasizes the importance of understanding the union of solutions, which results in all real numbers being valid solutions for the compound inequality.
