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){
    	Scanner input = new Scanner(System.in);
    	while(input.hasNextInt()){
    		int a = input.nextInt();
    		int b = input.nextInt();
    		int c = input.nextInt();
    		int d = input.nextInt();
    		int e = input.nextInt();
    		int f = input.nextInt();
    		
    		int oa = a;
    		a *= d;
    		b *= d;
    		c *= d;
    		e *= oa;
    		f *= oa;
    		
    		double x = 0;
    		double y = 0;
    		
    		if(b != e){
    			y = (double)(c-f)/(double)(b-e);
    		}
    		if(a != 0){
    			x = (double)(c-b*y)/(double)a;	
    		}
            if(x <= 0 && x > -0.0005)x = 0;
            if(y <= 0 && y > -0.0005)y = 0;
    		System.out.println(new BigDecimal(x).setScale(3, BigDecimal.ROUND_FLOOR)+" "+new BigDecimal(y).setScale(3, BigDecimal.ROUND_HALF_UP));
    
    	}
    }
