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

    private void rightTriangle() {
        Scanner sc = new Scanner(System.in);
        while (sc.hasNext()) {

            int b = sc.nextInt();
            int c = sc.nextInt();
            int d = sc.nextInt();
            int e = sc.nextInt();
            int f = sc.nextInt();
            float x = (float)(c * e - b * f) / (a * e - b * d);
            float y = (float)(c * d - a * f) / (b * d - a * e);
            System.out.println(String.format("%.3f %.3f",
                                             x == 0 ? 0 : x ,
                                             y == 0 ? 0 : y));
        }
