# Ch 9: ELM Test - Algebra: Absolute Value Equations & Inequalities

Review absolute value equations and inequalities in preparation for the ELM, CSU's math placement exam. This chapter covers systems of linear equations and equations involving the absolute value.

## ELM Algebra: Absolute Value Equations & Inequalities - Chapter Summary

Review for the ELM Math by learning the basics of absolute value equations and inequalities. The online video lessons in this chapter cover the follow mathematical topics:

• Solve linear equations (with both numerical and literal coefficients)
• Solve problems in context that are modeled by linear equations
• Solve systems of linear equations in two unknowns
• Solve equations involving absolute value (in one variable)

Watch the videos in this chapter to brush up on these important algebraic concepts. Then test your knowledge with an online quiz.

## ELM Objectives

The ELM is a math proficiency exam required for all incoming students to schools in the California State University system. You can learn more about the topics on the ELM here.

This Absolute Value Equations & Inequalities chapter is just one part of this course focused on Algebra. Approximately 35% of the ELM is devoted to algebra-based objectives. This chapter is best suited for the following objectives:

• Solve equations involving absolute value (in one variable)
• Solve inequalities involving absolute value (in one variable)

Other chapters in this course address other Algebra-based objectives, including:

• Evaluate and interpret algebraic expressions
• Use properties of exponents
• Perform polynomial arithmetic (add, subtract, multiply, divide and factor)
• Solve problems in context that are modeled by linear equations
• Solve quadratic and rational equations
• Find and use slopes and intercepts of lines

Understanding the concepts taught in this chapter will provide you with a solid foundation for the ELM Math.
