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) {
		// TODO Auto-generated method stub
		Scanner scan = new Scanner(System.in);
		while (scan.hasNext()) {
			double a = scan.nextInt();
			double b = scan.nextInt();
			double c = scan.nextInt();
			double d = scan.nextInt();
			double e = scan.nextInt();
			double f = scan.nextInt();

			double x;
			double y;

			x = ((c * e) - (f * b)) / ((a * e) - (d * b));
			y = ((c * d) - (f * a)) / ((b * d) - (e * a));
			System.out.printf("%.3f",x);
			System.out.print(" ");
			System.out.printf("%.3f",y);
		}
	}
