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;
import java.text.DecimalFormat;

class Main
{
	public static void main(String args[])
	{
		Scanner sc = new Scanner(System.in);
		
		DecimalFormat df = new DecimalFormat();
		df.applyLocalizedPattern("0.000");
		
		while (true)
		{
			try
			{
				double a = sc.nextInt();
				double b = sc.nextInt();
				double c = sc.nextInt();
				double d = sc.nextInt();
				double e = sc.nextInt();
				double f = sc.nextInt();
				
				System.out.print(df.format((e * c - b * f) / (a * e - b * d)) + " ");
				System.out.println(df.format((a * f - d * c) / (a * e - b * d)));
			}
			catch(Exception e)
			{
				break;
			}
		}
	}
