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.math.BigDecimal;

public class Main
{
    public static void main(String[] args)
    {
	Scanner cin = new Scanner(System.in);
	while(cin.hasNext())
	{
		double a = cin.nextInt();
		double b = cin.nextInt();
		double c = cin.nextInt();
		double d = cin.nextInt();
		double e = cin.nextInt();
		double f = cin.nextInt();
		BigDecimal xbd = new BigDecimal((c*e-b*f)/(a*e-b*d));
		BigDecimal ybd = new BigDecimal((a*f-c*d)/(a*e-b*d));
		BigDecimal x =  xbd.setScale(3, BigDecimal.ROUND_HALF_UP);
		BigDecimal y =  ybd.setScale(3, BigDecimal.ROUND_HALF_UP);
		System.out.println(x.doubleValue()+" "+y.doubleValue());
	}
    }
