How to solve inequalities on number line
WebFigure 3. A number line showing x ≤ 2. Example Suppose we wish to solve the inequality −2x > 4. In order to solve this we are going to divide both sides by −2, and we need to remember that because we are dividing by a negative number we must reverse the inequality. x < −2 There is often more than one way to solve an inequality. WebStep by step guide: Inequalities on a number line List integer values in a solution set We can list all of the integer values represented by an inequality E.g. List the integer values represented by 2<8 2 < x < 8 As ‘<’ means less than, the values of x x do not include the values given. ‘ 2 2 ’ and ‘ 8 8 ’ are not included in the solution set.
