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.
