Problem:
Simultaneous Equation Write a program which solve a simultaneous equation:   ax + by = c  dx + ey = f  The program should print x and y for given a , b , c , d , e and f (-1,000 ≤ a, b, c, d, e, f ≤ 1,000). You can suppose that given equation has a unique solution. Input The input consists of several data sets, 1 line for each data set. In a data set, there will be a, b, c, d, e, f separated by a single space. The input terminates with EOF. Output For each data set, print x and y separated by a single space. Print the solution to three places of decimals. Round off the solution to three decimal places. Sample Input 1 1 2 3 4 5 6
2 -1 -2 -1 -1 -5 Output for the Sample Input 1 -1.000 2.000
1.000 4.000 Sample Input 2 2 -1 -3 1 -1 -3
2 -1 -3 -9 9 27 Output for the Sample Input 2 0.000 3.000
0.000 3.000
