Solving One-Step Equations

This video tutorial covers lesson 26 on solving one-step equations using addition and subtraction. It begins with an introduction to the lesson and the importance of understanding basic equations. The tutorial demonstrates solving equations using both tape diagrams and algebraic methods, emphasizing the identity property. Several examples are provided, and students are encouraged to practice independently using both methods. The video also includes instructions for independent exercises and encourages students to use the pause feature to review examples.
