Linear Equations

We'll begin the solving portion of this chapter by solving linear equations.

Standard form of a linear equation:

A linear equation is any equation which can be written in the form

                                                     ax + b =0

where a and b are called as real numbers and x is a variable. It form is called the standard form of a linear equation. Note that mostly linear equations will not begin in this form.  Also, the variable may or may not be an x thus don't get too locked into seeing an x always there.
