This document provides an overview of linear equations in one variable. It defines key terms like algebraic expression, variable, equation, and linear equation. It then describes how to solve different types of linear equations in one variable by transposing terms to one side and using multiplication/division. Examples are provided for solving equations with the variable on one or both sides. The document also discusses using linear equations to solve word problems and provides step-by-step solutions for sample problems. Homework problems involving solving various linear equations are assigned at the end.
