We can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra), like this: If we subtract 3 from both sides, we get: And that is our solution: x …

Inequality is the relation between two numbers or mathematical expressions that make a non-equal comparison. Learn the process of solving different types of inequalities like linear inequalities, …

Here you will learn about inequalities, including comparing quantities using inequalities, interpreting inequalities, representing inequalities, and solving inequalities.

There are lots of strategies we can use to solve equations. Let's explore some different ways to solve equations and inequalities. We'll also see what it takes for an equation to have no solution, or infinite …

In these lessons, we will look at the rules, approaches, and techniques for solving inequalities. The rules for solving inequalities are similar to those for solving linear equations. However, there is one …

Learn how to solve inequalities in math with step-by-step examples, rules, and definitions. Perfect for students in the 2025-26 school year.

Algebraically: a > b if and only if a − b > 0. On the basis of this definition, we can prove various theorems about inequalities. Theorem 1. We may add the same number to both sides of an inequality, and the …

This chapter explains the properties of inequalities and then goes on to show how to solve linear and non-linear inequalities. Finally, we see how to solve inequalities that involve absolute values.
