Exploring Systems of Linear Equations

Professor Von Schmohawk explains how a race between a tortoise and a hare can be modeled using linear equations. The video covers solving these equations using substitution and elimination methods, and explores scenarios with different types of solutions: single, none, or infinite. It also discusses consistent and inconsistent systems, dependent and independent equations, and how to use slope-intercept form to determine solution types.

What method can be used to solve a system of linear equations?

• All of the above

• Graphing
