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.math.BigDecimal;
import java.util.Scanner;


public class Main {
	public static void main(String args[]) {
	    int a, b, c, d, e, f;
	    double x, y;
	    Scanner s = new Scanner(System.in);
	    while (s.hasNext()) {
	    	a = s.nextInt();
	    	b = s.nextInt();
		    c = s.nextInt();
		    d = s.nextInt();
	    	e = s.nextInt();
	    	f = s.nextInt();
	    	x = (c * e - b * f) / (a * e - d * b);
	        BigDecimal x2 = new BigDecimal(String.valueOf(x));
	        double x3= x2.setScale(3, BigDecimal.ROUND_HALF_UP).doubleValue();
        	y = (c * d - a * f) / (b * d - a * e);
	        BigDecimal y2 = new BigDecimal(String.valueOf(y));
	        double y3= y2.setScale(3, BigDecimal.ROUND_HALF_UP).doubleValue();
	        System.out.printf("%.3f %.3f\n", x3, y3);
	    }
	}
