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 NumberFormatException,
			IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String line;
		String[] lineArray;
		while ((line = br.readLine()) != null) {
			lineArray = line.split(" ");
			double[] f = new double[lineArray.length];
			for (int i = 0; i < lineArray.length; i++) {
				f[i] = (double) 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]);
			if (x == -0.0) {
				x = 0.0;
			}
			if (y == -0.0) {
				y = 0.0;
			}
			System.out.print(String.format("%.50f %.50f\n", x, y));
		}
	}
