Overview

Linear equations describe relations in which the highest power of the variable is one. The chapter builds from one-variable equations to two-variable equations, graphing, and systems of equations. It also shows how to solve word problems by turning statements into algebraic equations and then applyi

Key Concepts

A linear equation in one variable

A linear equation in one variable has the general form ax + b = 0, where a is not zero. Its solution is the value of the variable that satisfies the e

A linear equation in two variables

A linear equation in two variables has the general form ax + by + c = 0, where at least one of a or b is non-zero. Each solution is an ordered pair (x

The solution of a linear equation

The solution of a linear equation is the value of the variable that makes the equation true.

The same operation must be performed

The same operation must be performed on both sides of an equation to keep equality unchanged.

When a term is moved from

When a term is moved from one side of an equation to the other, its sign changes.

Learning Objectives

  • Identify linear equations in one variable and two variables.
  • Use the general forms ax + b = 0 and ax + by + c = 0 correctly.
  • Solve linear equations in one variable using balance and transposing methods.
  • Form equations from word problems involving ages, numbers, rectangles, and money.
  • Find and verify solutions of linear equations in two variables.
