Understanding Linear Equations

This video tutorial covers the three types of linear equations: conditional, identity, and contradiction. It explains each type with examples, demonstrates how to solve them, and verifies solutions graphically. Conditional equations have specific solutions, identity equations have infinite solutions, and contradiction equations have no solutions. The tutorial also provides numerical verification methods.
