4.6 Taking Sides – A Practice Understanding Task. Solving linear inequalities and representing the  If your finite math instructor asks you to solve a linear inequality, you can use most of the same rules that you'd use when solving linear equations. There are two  Solving Inequalities. Please work with a partner on this exercise. The purpose of this excercise is to review vertical shifts and reflections, solving quadratic  A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables.

Multiplying or dividing an inequality by a negative number changes the inequality symbol. Solving Inequalities: An Overview (page 1 of 3) Sections: Linear inequalities, Quadratic inequalities , Other inequalities Solving linear inequalities is very similar to solving linear equations , except for one small but important detail: you flip the inequality sign whenever you multiply or divide the inequality by a negative.

Lesson . 5. Forming and solving inequalities (Part 1) Chapter 6 Solving Linear Inequalities 316D If the solution is an untrue statement, such as 4 8, there is no solution. If the solution results in a statement that is always true, such as 5 3, then the solution is the set of all real numbers. A solution can always be checked by substituting it back into the inequality.

If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions. Use the sign of each side of 

Inequalities with variables on both sides. In this unit, we learn how to solve linear equations and inequalities that contain a single variable. For example, we'll solve equations like 2(x+3)=(4x-1)/2+7 and inequalities like 5x-2≥2(x-1). Gives an overview of inequality solving techniques, according to the type of inequality. This page covers polynomial and rational inequalities.
