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: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner s = new Scanner(System.in);
		while (s.hasNextDouble()) {
			int[] n = new int[6];
			for (int i = 0; i < 6; ++i) {
				n[i] = s.nextInt();
			}
			double d = n[0] * n[4] - n[1] * n[3];
			System.out.printf("%.3f %.3f\n", (double)Math.round((n[2] * n[4] - n[1] * n[5]) * 1000 / d) / 1000, (double)Math.round((n[0] * n[5] - n[2] * n[3]) * 1000 / d) / 1000);
		}
	}
