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)
	{
		Scanner scanner = new Scanner(System.in);
		do
		{
			int a = scanner.nextInt(); //a1
			int b = scanner.nextInt(); //b1
			int c = scanner.nextInt(); //c1
			int d = scanner.nextInt(); //a2
			int e = scanner.nextInt(); //b2
			int f = scanner.nextInt(); //c2
			double x = (double)(c*e - f*b) / (a*e - d*b);
			double y = (double)(a*f - d*c) / (a*e - d*b);
			//x = (c1b2 - c2b1) / (a1b2 - a2b1)
			//y = (a1c2 - a2c1) / (a1b2 - a2b1)
			System.out.println(String.format("%.3f %.3f", (double)((int)x), (double)((int)y)));
		}
		while(scanner.hasNext());
