Solving Compound Inequalities Challenge

The video tutorial covers solving and graphing compound inequalities. It begins with a review of simple inequalities and progresses to compound inequalities, including both 'and' and 'or' types. The instructor demonstrates solving these inequalities step-by-step and graphing their solutions on a number line. Key concepts such as flipping inequality signs when dividing by negative numbers are also explained.

What is the first step in solving the inequality 80 > 4x + 12?
