Solving Equations and Inequalities with Absolute Value

The concept of absolute value can be difficult for learners to grasp. Reinforce their understanding of a basic absolute value expression and connect it to solving equations and inequalities. Scholars write two equations/inequalities to find the two solutions or endpoints. They then write and graph the inequality solutions.
