Create a Table of Values from an Equation

This video tutorial teaches how to solve equations with two variables using substitution. It begins with a simple equation, x + y = 7, demonstrating how to create a table of values by substituting different values for x and y. The tutorial then progresses to a more complex equation, x^2 + y^2 = 25, showing how to solve it by taking square roots and considering both positive and negative solutions. The importance of checking solutions in the original equation is emphasized throughout.
