Solving linear inequalities is similar to solving linear equations , but with the following differences: Typically, an inequality has infinitely many solutions , and the solution set is often written in interval form . WARNING 1 : We must reverse the direction of the inequality sign if we switch the sides of an inequality, or if we multiply or divide both sides by a negative number.
