This video tutorial demonstrates how to solve inequalities using the Virginia version of Desmos, which is tailored for the state's standards of learning tests. It covers the basic steps for solving inequalities, including identifying dotted and solid lines and shading directions. The tutorial also addresses how to handle errors, such as unrecognized variables, and explains special cases like no solution or all real numbers, which require manual solving.
