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: Accepted)

import java.util.Scanner;

class Main {

    public static void main(String[] args){
	Scanner stdin = new Scanner(System.in);
	int[] nums = new int[6];
	final int a = 0;
	final int b = 1;
	final int c = 2;
	final int d = 3;
	final int e = 4;
	final int f = 5;
	
	
	while(stdin.hasNextInt()){
	    for(int i = 0; i < 6; i++){
		nums[i] = stdin.nextInt();
	    }

	    double y = (double)(nums[d] * nums[c] - nums[a] * nums[f]) /
		(nums[d] * nums[b] - nums[a] * nums[e]);
	    double x = (nums[c] - nums[b] * y) / nums[a];
	    System.out.printf("%.3f %.3f\n", x, y);
	}
    }
