Section 4-1: Introduction to Linear Systems

To understand and solve linear systems.

A system of equations or inequalities is a set of open sentences each of which contains the same variables.

The solution set of a system with two variables is the set of all ordered pairs that satisfy all the open sentences in the system.

Section 4-2: Solution of Systems of Linear Equations

Given a system of two linear equations in two variables, solve it by transforming it to an equivalent system of the form: x= constant y= constant

Solve the system:
