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) {
		// TODO ?????????????????????????????????????????????
		Scanner s = new Scanner(System.in);
		int[] a = new int[6];
		String str ;

		double x,y;
		
	
		while(s.hasNext()){

			
			for(int i = 0; i < a.length;i++)
			{
				a[i] = s.nextInt();
			}
			 y = (a[2]*a[3]-a[5]*a[0])/(a[1]*a[3]-a[4]*a[0]);
			 x = (a[2]-a[1]*y)/a[0];
			 System.out.printf("%.3f %.3f\n",x,y);

			
		}
