Understanding Systems of Equations

The video tutorial explains the three types of solutions for systems of equations: consistent and independent (one solution), consistent and dependent (infinite solutions), and inconsistent (no solution). It provides examples and graphing instructions for each type, highlighting the characteristics of each system and how to identify them on a graph.

What is the term used for a system of equations with exactly one solution?

• Consistent and independent

• Consistent and dependent

• Dependent

• Inconsistent
