An inequality is a sentence with <, >, ≤, or ≥ as its verb. An example is 3x - 5 < 6 - 2x. To solve an inequality is to find all values of the variable that make the inequality true. Each of these numbers is a solution of the inequality, and the set of all such solutions is its solution set. Inequalities that have the same solution set are called equivalent inequalities.
