How to Divide Inequalities. Part of the series: Math Fractions and Equations. When dividing inequalities, treat the equation like any other standard equation. Flip the inequality sign when dividing an inequality by a negative number with help from a ...math author and teacher.[more]

This video shows how to solve an inequality to find the range of correct values for the variable. The sample problem the instructor presents especially focuses on what to do with the inequality symbol when you have to multiply both sides of the ineq...uality by a negative number. Then, the instructor shows how to put the answer on a number line and how to express the answer using set notation.[more]

Instructor uses a white board to demonstrate solving inequalities in one variable and graphing the solution on a number line. Examples include one-step, two-step, and multi-step linear inequalities.

A teacher walks students through the explanation of how to solve four different mult-step one variable inequalities. This includes using the distributive property, combining like terms first, and check if a value is a solution.

The instructor uses an electronic chalkboard to demonstrate how to solve a multi-step inequality. One example is modeled using a step by step approach to solve for x and reversing the inequality symbol when dividing by a negative is shown.

This video shows examples of inequalities with one variable and the instructor goes through the steps necessary to solve the inequalities. While he does this, he explains some of the important rules necessary for correctly solving inequalities. He ...also identifies some common mistakes students make when solving inequalities.[more]

In this video, the instructor defines linear inequalities then provides some examples which he solves showing each necessary step. He starts with very simple examples, then moves on to more difficult problems. He also reiterates that linear inequal...ities are solved in a similar manner to regular equations, but quadratic inequalities are not solved in the same way as quadratic equations.[more]

The instructor uses an electronic sketchpad to demonstrate how to solve linear inequalities in one variable. This video is part 1 of 2 and several problems are solved and plotted on a number line.
