In this chapter, we explore the idea of equality. The Properties of Equality are introduced as a way to maintain equality while manipulating equations. We use these concepts to show that solving equations can help us find the value(s) of a variable that makes an equation true.
To start, we will solve one-step and multi-step equations by using inverse operations, the Distributive Property, combining like terms, and dealing with variables on both sides of an equation.
These methods will also be applied to literal equations — equations with more than one variable. Finally, we create and solve one-variable equations to solve situations in context.
