Solving Inequalities Using Addition or Subtraction
An inequality is a statement formed by placing an inequality symbol between two expressions. For example, y + 5 ≤ ˉ6 is an inequality.
The solution of an inequality with a variable is the set of all numbers that produce true statements when substituted for the variable. You can show the solution of an inequality by graphing the inequality on a number line. When you graph an inequality of the form x > a or x < a, use an open circle at a. When you graph an inequality of the form x ≥ a or x ≤ a, use a closed circle at a.
