Demonstrates the Gauss-Jordan form of solving a 3 x 3 System of Equation
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.
