Linear Systems

Linear Systems

In this chapter, we present systems of equations as groups of two or more equations that are analyzed/solved simultaneously. The solution set of a system lies on the point (or points) at which every equation in the system is true. Systems of linear equations can have zero, one or infinitely many solutions, depending on the ways in which the lines relate.

To solve linear systems graphically, we will find the point or points where the lines intersect. We will also solve linear systems algebraically, using the substitution and elimination methods. Finally, systems of linear inequalities and their solutions will be introduced.
