Using Algebra Tiles to Solve Equations

This tutorial demonstrates how to solve equations using algebra tiles. It begins with setting up the equation 3j - 5 = 19 using tiles to represent variables and constants. The tutorial then shows how to balance the equation by adding and removing tiles to isolate the variable. Finally, it explains how to determine the value of the variable, resulting in the solution j = 8.
