The video tutorial explains how to solve two-step equations using a tile model. It begins with an introduction and acknowledgment of resources. The instructor models the equation 2x + 1 = 3 using tiles, demonstrating how to balance both sides. The process involves isolating the X tiles by creating zero pairs and subtracting equally from both sides. Finally, the instructor divides the tiles to find the value of X, completing the solution. The tutorial emphasizes the subtraction and addition properties of equality.

What is the first step in solving a two-step equation?
