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.*;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		double a,b,c,d,e,f;
		double x,y;
		while(sc.hasNext()){
			a = sc.nextDouble();
			b = sc.nextDouble();
			c = sc.nextDouble();
			d = sc.nextDouble();
			e = sc.nextDouble();
			f = sc.nextDouble();
			x = (c*e - b*f)/(a*e - b*d);
			y = (c*d - a*f)/(b*d - a*e);
			BigDecimal bi = new BigDecimal(String.valueOf(x));
			double x1= bi.setScale(3, BigDecimal.ROUND_HALF_UP).doubleValue();
			BigDecimal ai = new BigDecimal(String.valueOf(y));
			double y1= ai.setScale(3, BigDecimal.ROUND_HALF_UP).doubleValue();
			System.out.printf("%3f %3f",x1,y1);
		}
