Algebra 36 - Solving Systems of Equations by Substitution

Professor Von Schmohawk introduces a lecture on finding the intersection point of two graphs using the substitution method. The lecture recaps a race between a tortoise and a hare, where the hare catches up to the tortoise. The professor explains how to use equations to determine the exact time and distance when they meet. The substitution method involves replacing one variable in an equation with another to solve for a unique value. The lecture concludes with a preview of the elimination method for solving systems of equations.

What are the coordinates of the intersection point of the two graphs?

What elapsed time and distance do the intersection point values represent?

What will be introduced in the next lecture regarding solving systems of equations?
