The phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is the graph of the function of x that has been defined in the preceding section. If b = 0, the line is a vertical line (that is a line parallel to ...

Systems of linear equations and their solution, explained with pictures , examples and a cool interactive applet. Also, a look at the using substitution, graphing and elimination methods.
A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.
Now we will work with two or more linear equations grouped together, which is known as a system of linear equations. In this section, we will focus our work on systems of two linear equations in two unknowns (variables) and applications of systems of linear equations.
