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.io.*;

public class Main{
	public static void main(String[] argv) throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String line;
		String[] lineArray;
		while((line = br.readLine()) != null){
			lineArray = line.split(" ");
			int[] f = new int[lineArray.length];
			for(int i=0; i<lineArray.length; i++){
				f[i] = Integer.parseInt(lineArray[i]);
			}
			double x = (f[4]*f[2]-f[1]*f[5])/(f[0]*f[4]-f[1]*f[3]);
			double y = (-f[2]*f[3]+f[0]*f[5])/(f[0]*f[4]-f[1]*f[3]);
			
			System.out.print(String.format("%.3f %.3f", x, y));
		}
	}
