Learn algebra online with Khan Academy, covering equations and inequalities through engaging lessons and exercises to enhance your understanding.

Sal solves several multi-step linear inequalities. Look at an example with just numbers. Consider: -2 < 5 This is currently a true statement. Now, multiply both sides by -1. -- If you don't reverse the …

We will now equate two algebraic expressions and think about how it might constrain what value the variables can take on. The algebraic manipulation you learn here really is the heart of algebra.

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).

This topic covers: - Solutions to linear inequalities and systems of inequalities - Graphing linear inequalities and systems of inequalities - Linear inequalities and systems of inequalities word problems

Bring on the algebra! Learn how to manipulate expressions and solve equations and inequalities.

If you can solve equations that have the variable on both sides, then you can solve these. You use the same exact techniques. The only things that are different are: 1) If you multiply or divide both sides …

A multi-step inequality has more than one operation in it, for example 2 x 5> 7 . A compound inequality is the combination of two inequalities, for example x> 3 AND x <7 . Practice with our Multi-step linear …

Types of linear inequalities The steps for solving linear inequalities are similar to those for solving linear equations. For inequalities, we have to pay attention to the direction of the inequality signs.
