Chapter 9: Systems of Linear Equations
Introduction
Systems of equations means there are 2 (or more) equations with the same variables.
To solve systems of equations, you must find all ordered pairs that make both equations true.
In this chapter, you will learn 4 methods of solving systems of equations.
The Graphing Method
The Substitution Method
The Addition-or-Subtraction Method
Multiplication with the Addition-or-Subtraction Method
We will also learn to set up systems of equations in order to solve problems.
