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.*;

public class Main {

	/**
	 * @param args
	 */

	static void solve(int[] a){
		double d = a[0]*a[4]-a[1]*a[3];
		System.out.println(
				((double)a[4]*a[2]-a[1]*a[5])/d
				+" "+
				((double)-a[2]*a[3]+a[0]*a[5])/d
				);
	}

	public static void main(String[] args) {
		// TODO 自動生成されたメソッド・スタブ

		Scanner scan = new Scanner(System.in);

		while(scan.hasNext()){
			int[] a= new int[6];
			for(int i=0;i<6;i++){
				a[i]=scan.nextInt();
			}
			solve(a);
		}
	}
