Not everything in the world is equal, and it's true of equations, too! A linear inequality is like a linear expression, only it has an inequality sign in it. Their solutions are often graphed. In this group of tutorials we'll explain everything you need to know about solving linear inequalities, including the trick of multiplying and dividing by negative numbers to solve them. Common Core Standard: 7.EE.B.4b
Our discussion of linear inequalities begins with multiplying and dividing by negative numbers. Listen closely for the word "swap." Super important!
In addition to solving the inequality, we'll graph the solution. Remember to swap if you mutiply both sides of the inequality by a negative number.
Inequalities are more than abstract concepts and exercises. They help solve real life problems. Here's an example.
Solve inequalities in one step.
Solve 2-step inequalities like 3x + 2 > 5.
We're turning up the heat a little and asking you to help us solve a multi-step inequality problem.
We'll talk you through this fun and challenging inequality problem.
Here's an opportunity for you to follow along with us as we interpret, construct, and solve a word problem inequality. It will be fun!
Let's tackle this word problem together. We'll interpret the information and then construct a linear inequality to solve it.
Constructing, interpreting, and solving linear equations based on context.
