If you already know how to solve first-degree inequalities: • First-degree inequalities from scratch Polynomial inequalities: • Polynomial inequalities from scratch And rational inequalities: • Rational inequalities from scratch In this video I explain how to solve systems of inequalities with one unknown, solving several examples step by step. Firstly, you have to solve each inequality in the system independently. The solution to the system will be the intersection (the common piece) of all the solutions.
