This is a free lesson from our course in Algebra I This lesson explains how to solve inequalities. The basic rule for solving a given inequality is similar to that for solving equations -- do the same operation to both sides of inequality. The lesson explains this in detail with examples. Note: If you multiply or divide an inequality on both sides by a negative number, then you need to flip the direction of the inequality symbol. The solution to an inequality is a value that makes the inequality true. You can solve inequalities in the same way you can solve equations, by following these rules.� You may add any positive or negative number to both sides of an inequality.� You may multiply or divide both sides of an inequality by any positive number.If you multiply or divide both sides of an inequality by a negative number, reverse the direction of the inequality sign.
