hi
This program will solve a simple equation in the form ax+b=cx+d for x.
At the beginning you will enter a,b,c, and d. (a and c are coeffecients)
If "THIS IS AN IDENTITY" is shown, any real number x will make the equation true.
If "NO SOLUTIONS" is shown, any real number x will make the equation false.
When asked if you want it to show work, press LOG (green n) to just have the calc show the solution.  
If you press 1 (green y) it will show the work step by step.
(Note: the number in the left is the coeffecient of x.)
(Note: if you use the work shower, keep the number of digits in a,b,c,d down to four (includes decimal places) and put the mode on 0 or Float)

Hope you find this more convenient than the guess and check nature of the built in equation solver!!!!!!

ENJOY!!!!!!!!!
