Linear Inequalities One Variable Mr Williams Math Class Solve linear inequalities and then graph the solutions on a number line. express answers using interval notation. all steps are provided. In this section, we will study linear inequalities in one variable. inequalities can be used when the possible values (answers) in a certain situation are numerous, not just a few, or when the exact value (answer) is not known but it is known to be within a range of possible values.
Openalgebra Linear Inequalities One Variable In the following video, you will see an example of solving a linear inequality with the variable on the left side of the inequality, and an example of switching the direction of the inequality after dividing by a negative number. All but one of the techniques learned for solving linear equations apply to solving linear inequalities. you may add or subtract any real number to both sides of an inequality, and you may multiply or divide both sides by any positive real number to create equivalent inequalities. The basic steps for solving a linear inequality in one variable are outlined next. they are identical to the thought process for solving linear equations, with the new idea of changing the direction of the inequality if you multiply or divide by a negative number. The technique to use when solving linear inequalities is to isolate the variable on one side. remember to reverse the direction of the inequality symbol when multiplying or dividing both sides of an inequality by a negative number.

Definition replacing the equal sign in the general linear equation · x b = c by any of the symbols <, ≤, > or ≥ gives a linear inequality in one variable. for example, 2 · x − 1 ≤ 0 and 3x 5 > 8 are two different linear inequalities in a single variable, x. There are three ways to represent solutions to inequalities: an interval, a graph, and an inequality. because there is usually more than one solution to an inequality, when you check your answer you should check the end point and one other value to check the direction of the inequality. Solving an inequality means, isolating the variable, and then graphing the solution on a number line, or writing the solution in the interval or set builder notation.
