Solving Equations Using a Balance Scale

This video tutorial teaches how to solve simple equations using a balance scale method. It covers the concept of inverse numbers leading to zero, substitution to verify solutions, and the importance of maintaining balance by adding the same value to both sides of an equation. The tutorial also explains solving two-step equations and handling equations with negative coefficients, emphasizing the need to isolate the variable and divide into equal groups.
