Introduction to Solving Systems of Equations

Graphing/Substitution/Elimination

Three Methods for Solving Systems

Which method you use depends on what form(s) your equations are in.

Solving Systems By Graphing

This method works best with equations in slope-intercept form, when you have graph paper or a graphing calculator.

What is the solution for this system of equations? Be sure to write your answer as an ordered pair.

Solving Systems Using Substitution

Use this method when one or both equations are or are easily solved for one of the variables.

Solve Systems Using Elimination

Use this method when your equations are or are easily written in the same format. This is easiest when one set of terms "matches".
