Algebra I • Unit 3: Linear Equations

Solving Linear Equations

A linear equation is an equation where the highest power of the variable is 1. These equations form straight lines when graphed and are foundational to algebra. In this lesson, we'll learn how to solve them step by step.

Definition: A linear equation in one variable has the form , where a, b, and c are constants and a is not zero.

Example: Solve for x
