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.NoSuchElementException;
import java.util.Scanner;


public class Main {

	public static void main(String[] args) {
		double a[];
		double ans[];
		a = new double[6];
		ans = new double[2];
		for(int i=0;i<6;i++){
			a[i]=0;
		}
		Scanner scan = new Scanner(System.in);
		while(true){
			try{
				for(int i=0;i<6;i++){
					a[i]=scan.nextInt();
				}
				ans = cal(a);
				System.out.print(String.format("%.3f", ans[0]));
				System.out.print(" "+String.format("%.3f", ans[1]));
			}catch(NoSuchElementException ex){
				break;
			}
		}

	}

	private static double[] cal(double a[]){
		double ans[] = new double[2];
		ans[1]=(((a[2]*a[3])/a[0])-a[5])/(((a[1]*a[3])/a[0])-a[4]);
		ans[0]=(a[5]-a[4]*ans[1])/a[3];
		return ans;
	}
