CK-12: Andrew Gloag, Anne Gloag, and Eve Rawley's "Applications of Linear Systems"

Read the entire text, and watch the videos embedded in the text. (You may skip Example B, as you have already seen it in subunit 6.1.6.) This reading discusses a variety of real-world situations which can be described by systems of linear equations. Note that some of these systems can be inconsistent or dependent, and you will learn to interpret what this means in the context of the given situation. After reading, complete practice problems 1-10. Once you have completed the practice problems, check your answers against the answer key.
