Demonstrates the row echelon form of solving a 3 x 3 System of Equation which has been used by the Chinese for over 1800 years (commonly called the Gaussian Elimination). These are the beginning steps for the reduced row echelon form known as the Gauss-Jordan Elimination.
The user will enter the coefficients and constant of three linear equations in three variables; from this point on the use will enter row multipliers which will allow them to eliminate (make zero) coefficients for x in the second and third rows...with step 2 eliminate the y coefficient in the third row. Finally, the user will enter divisors on each row to make the leading non-zero value 1.
