Key Concepts

Linear Equations

A linear equation is an equation in which the variable appears only to the first power and the graph of the equation is a straight line. It typically has the form ax + b = c, and solving these equations involves finding the value of the variable that makes the equation true.

Properties of Equality

The properties of equality state that if you perform the same operation (such as addition, subtraction, multiplication, or division) on both sides of an equation, the equality remains intact. This principle is essential when solving for the variable in an equation.

Inverse Operations

Inverse operations are used to undo or reverse the effects of another operation. When solving linear equations, applying inverse operations allows you to isolate the variable by cancelling out the added or subtracted numbers from one side of the equation.
