Unformatted text preview: ± ” (is less than or equal to) or the “ ± ” (is greater than or equal to) signs. Inequations involve the “ ± ” (is not equal to) sign. 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. Solving inequations is also similar to solving equations, although “ ± ” never needs to be reversed....
