Solving and graphing a compound inequality- Math Help

The video tutorial explains how to handle compound inequalities by separating them into two distinct inequalities. The instructor demonstrates solving these inequalities for the variable X and graphing the solutions on a number line. The concept of 'and' statements is introduced, emphasizing the importance of reading inequalities correctly. The tutorial concludes with identifying the intersection of the inequalities, which represents the solution set on the graph.
