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

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.*;
public class Main{
    public static void main(String[] args){
	new Main().run();
    }
    Scanner sc = new Scanner(System.in);

    int a, b, c, d, e, f;
    double x, y;

    void run(){
	while(sc.hasNext()){
	    a = sc.nextInt();
	    b = sc.nextInt();
	    c = sc.nextInt();
	    d = sc.nextInt();
	    e = sc.nextInt();
	    f = sc.nextInt();

	    x = (double)(c*e-b*f)/(a*e-b*d);
	    y = (double)(a*f-c*d)/(a*e-b*d);
	    if(x==(-0.0)) x = Math.abs(x);
	    if(y==(-0.0)) y = Math.abs(y);
	    System.out.println(x+" "+y);
	}
    }
}
