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.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {

public static void main(String args[]) {
    	
    	InputStreamReader isr = new InputStreamReader(System.in);
    	BufferedReader br = new BufferedReader(isr);
    	String buf;
    	int a,b,c,d,e,f;
    	double x,y;
    	
    	try{
    		while((buf = br.readLine())!=null)
    		{
    			StringTokenizer st = new StringTokenizer(buf);
    			a = Integer.parseInt(st.nextToken());
    			b = Integer.parseInt(st.nextToken());
    			c = Integer.parseInt(st.nextToken());
    			d = Integer.parseInt(st.nextToken());
    			e = Integer.parseInt(st.nextToken());
    			f = Integer.parseInt(st.nextToken());
    			x = (e*c-b*f)/(a*e-b*d);
    			y = (-d*c+f*a)/(a*e-b*d);
    			System.out.println(String.format("%.3f", x)+" "+String.format("%.3f", y));
    			
    		}
    	} catch (Exception err){
    		System.out.println("Exception");
    	}
    	
    }
