 * Program Name:        Inclass01A
 * Program Description: This program uses Cramer's rule to calculate the values
 *                      of x and y for two linear equations.
 *                      If:
 *                          ax + by = e
 *                          cd + dy = f
 *                      Then:
 *                              x = ( ed - bf ) / ( ad - bc )
 *                          and y = ( af - ec ) / ( ad - bc )
