Solving Equations Containing Absolute Value
Algebra Lesson 3
How do you solve equations involving absolute value?
To solve an equation containing an absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations.
After completing this tutorial, you should be able to:
Know what an equation is
Know if a value is a solution or not
Know what a solution set of an equation means
Know the different types of equations
Use the different properties of equality to solve linear equations.
Determine the solution set of a linear equation
The heart of algebra is about solving equations. In this tutorial we will be looking specifically at linear equations and their solutions. We will solve equations that use only one property to make sure you have the individual concepts down. Then we will mix them up where you need to use several properties and steps to get the job done.
Equations can be used to help us solve a variety of problems. In later tutorials, we will put them to use to solve word problems. Then you can answer those tricky math questions.
