Solving Two-Step Equations with Algebra Tiles

The video tutorial demonstrates how to solve equations using algebra tiles. It begins with an introduction to algebra tiles and their use in solving equations. The instructor then provides a detailed walkthrough of solving the equation 2x + 2 = 4, explaining the concept of zero pairs and isolating variables. The tutorial continues with another example, solving 3x + 5 = -7, emphasizing the importance of balancing equations by adding negatives to both sides. The video concludes by encouraging viewers to practice solving additional equations using the techniques demonstrated.
