This Instructional Activity is a part of the Lesson 22, Unit 2, Grade 7. In this lesson, you will transition from solving equations using tape diagrams to solving equations algebraically by making zero (using the additive inverse) and making one (using the multiplicative inverse). Justify your work by identifying which algebraic property you used for each step in solving the problems. Explain your work by writing out how you solved the equations step by step and relate each step to those used with a tape diagram.
