# Ch 6: Algebra II: Systems of Linear Equations

Watch online math video lessons and learn about linear systems, the substitution and elimination methods, intersection points and more. These video lessons are short and engaging and make learning easy!

## Algebra II: Systems of Linear Equations - Chapter Summary and Learning Objectives

Now that you've got a linear equations review under your belt, use this chapter to find out what happens when you need two or more linear equations to solve the same problem. Instructors teaching the video lessons help you explore linear systems' uses to compare data; they also illustrate steps for solving linear systems and comparing their graphs. This chapter is designed to teach you how to:

• Set up a system of equations to solve a word problem
• Solve systems of equations containing two or more unknowns
• Solve linear systems with infinite solutions
• Solve linear systems with no solutions
