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

public class Main {
 
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        while(s.hasNext()) {
            double a = s.nextDouble();
            double b = s.nextDouble();
            double c = s.nextDouble();
            double d = s.nextDouble();
            double e = s.nextDouble();
            double f = s.nextDouble();
             
            double x = (e*c - b*f)/(a*e - d*b);
            double y = (d*c - a*f)/(b*d - a*e);
            if(x == -0.0) {
                x = 0;
            }
            if(y == -0.0) {
                y = 0;
            }
            System.out.printf("%.3f %.3f\n",x,y);
        }
