Solving an Equation Using Addition & Subtraction | 7.EE.B.4 💚

In this video lesson we will learn how to solve equations using addition and subtraction. We will first learn how to represent an equation using algebra tiles. We will then model how to solve an equation using algebra tiles by creating zero pairs. We will also check our solutions to ensure we are correct. We will learn about the Addition Property of Equality and the Subtraction Property of Equality and use them both to solve equations algebraically. We will solve equations using inverse operations which are operations that undo each other. We will also check our solutions to ensure we are correct. Student practice is embedded in the lesson with modeled exemplar solutions.
