Solving One Step Equations with Algebra Tiles

The video tutorial explains how to solve one-step equations using visual models. It introduces the concept of using colored squares and bars to represent numbers and variables, and demonstrates solving various equations by manipulating these models. The tutorial covers changing signs when crossing the equal sign, combining positive and negative values to zero, and dividing or multiplying to isolate variables.
