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.Scanner;

public class Main{

	public static void main(String[] args){
		@SuppressWarnings("resource")
		Scanner sc = new Scanner(System.in);
		while(sc.hasNextLine()){
			String[] s = sc.nextLine().split("[\\s]+");
			int a = Integer.parseInt(s[0]);
			int b = Integer.parseInt(s[1]);
			int c = Integer.parseInt(s[2]);
			int d = Integer.parseInt(s[3]);
			int e = Integer.parseInt(s[4]);
			int f = Integer.parseInt(s[5]);

			double x=(c*e-b*f)/(double)(a*e-b*d);
			double y=(c*d-a*f)/(double)(b*d-a*e);
			if(-0.0004<x&&x<=0)x=0;
			if(-0.0004<y&&y<=0)y=0;
			System.out.printf("%4.3f %4.3f",x,y);
		}
	}
