Solution of a system of equations:
It is an ordered pair of numbers that is a solution of both equations in the system.

Methods to solve a system of equations:
Graphing, substitution, addition and matrix techniques are the methods to solve a system of equations.

The point of intersection of two equations:
The point in which any two equations in a system of equations meet..

System of inequalities:
Multiple inequalities form a system of inequalities.

Multiple equations composed systems of equations. Systems of equations are solved through the use of solving methods. Solutions to systems of equations have characteristics that are shown through the use of examples.

Systems of inequalities are shown in some examples with their graphs. Solving systems of inequalities have created an importance interest to individuals who want to find the most efficient way to operate a business. Systems of inequalities cannot be graph using graphing calculators due to their subtleties.
