A system of equations is called an inconsistent system of equations if there is no solution because the lines are parallel. A dependent system of equations is when the same line is written in two different forms so that there are infinite solutions. These two situations occur when trying to solve for a system of equations.
Consistent and independent systems, consistent and dependent systems, and inconsistent systems
Solving Systems using Matrices
A system of equations is two or more equations that contain the same variables. Solving systems using matrices is one method to find the point that is a solution to both (or all) original equations. Besides solving equations using matrices, other methods of finding the solution to systems of equations include graphing, substitution and elimination.

Systems of Inequalities
When solving systems of inequalities, you are solving for a solution region. A solution region is the collection of points that are solutions to both inequalities. Solving systems of inequalities combines knowledge of graphing lines, graphing inequalities and solving systems of equations.
