The Basics

A System of Equations is a set of two equations that have the same unknown variable. The solution to the equations is the intersection point of the two lines

Jeopardy Problems


It is best to use substitution when one of the equations can be easily solved for one variable or is already isolated.


You can use elimination when one of the coefficients for both equations are the same or when the signs for the coefficients are opposites.


It is good to use graphing when the two equations are in slope-intercept form or when the equations can be easily isolated.
