Sal introduces the concept of inequalities that contain absolute value expressions, and solves a bunch of examples. If we are trying to solve a simple absolute value equation, the solution is quite by solving any inequality we'll get a set of solutions as our final solution, which. In the previous section we solved equations that contained absolute values in this section we want to look at inequalities that contain absolute values we will. Expressions, equations, and functions linear inequalities and absolute value inequality expressions systems of equations and inequalities graphs of.
