Solving a system of equations with a TI-83/84

Author: Christopher Danielson

Introduction

This packet assumes that you know how systems of equations are represented as matrices and that you know the rules for solving systems of equations by elimination and with matrices.

This is a technology packet-it gives explicit instructions for using a TI-83 or TI-84 to solve a system of equations with matrices.

Entering your matrix

This video gives explicit instructions for entering your system of equations as a matrix into the calculator.

Getting the calculator to solve the system

This video demonstrates the explicit instructions for having the TI-83 or 84 put a matrix in reduced row-echelon form, which solves the system of equations.
