Solving Linear Systems of EquationsA series of free Basic Algebra Lessons from Brightstorm online Algebra series.
Introduction to Systems of Equations A system of equations is two or more equations that contain the same variables. A solutions to a system of equations are the point where the lines intersect. There are four methods to solving systems of equations: graphing, substitution, elimination and matrices. Solving systems of equations is an important concept that shows up first in Algebra I, but is built upon in upper-level math.
Solving Systems of Equations by Graphing A system of equations is two or more equations that contain the same variables. Solving systems of equations by graphing is one method to find the point that is a solution to both (or all) original equations. Besides solving systems of equations by graphing, other methods of finding the solution to systems of equations include substitution, ,elimination and matrices.
