--Installation--
	Send SOLVE.8xp to your TI-83+.  Run the program.  after that its 
pretty self explanitory.  For the two or more variable part just input 
the constants one at a time, left to right from the first equation.  Make 
sure you dont change the order on one of the equations.


--Program Info--

	This program is very useful for solving equations.  This program 
will solve equations with one variable, two variables, and three variables.  
It also solves inequalities with one variable.  All the answers are shown 
in decimal form and fraction form (if there is any).  I found this program 
very useful in math classes.  

	For the 1 variable solver I separated the equation in two for the 
part before and the part after the = or other symbols (>,<,etc).  Then I 
used solve( to solve the equation.  Then I tried the equation with x being 
1 more or 1 less than the answer to find out whether the answer is = or < 
or >, etc.  

	For the 2 or more variable solver you have to input the equations as
aX + bY + cZ =N or however many variables there are.  Then the program uses 
the rref([A]) to solve the equation.


--Version Info--

v2.3  - This Version - Changed the program so it can do one variable "not 
      equal to" equations.  (uploaded)

v2.2  Fixed a bug in the answer evaluation (it works now!) (not uploaded)

v2.1  Added the "answer evaluation" (so you can view the answer as a frac or 
      round it) (not uploaded)

v2.0  Changed it so you can sovle an equation with unlimited variables as 
      long as you have enough mem and you have the same number of equatoins 
      as variables (uploaded)

v1.1  made smaller, and a few other minor changes (not uploaded)

v1.0 - First Release - Solves 1, 2, and 3 variable equations as well as
         1 variable inequalities (uploaded)


--Author/Disclaimer--
This program was written by Richard Fillman (me!).  It is ok to use some of 
the code but at least give me credit!  Even if you only use the idea and use 
your own code give a little credit!

-I am not responsible for any damage done to your mem or your calc itself 
(though ive never heard of a basic program messing with your mem!)



--Extra!--
I hope you find this program useful!  (I did)  If you have problems with 
this program you can e-mail me at:  kentaro1087@hotmail.com
