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;


public class Main{
	public static void main(String[] args) {
        InputStreamReader isr = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(isr);
   	    try{
   	    	String buf;
          while((buf = br.readLine()) != null){
        	double a,b,c,d,e,f;
            String[] co = buf.split("\\s");
            a = Double.parseDouble(co[0]);
            b = Double.parseDouble(co[1]);
            c = -1*Double.parseDouble(co[2]);
            d = Double.parseDouble(co[3]);
            e = Double.parseDouble(co[4]);
            f = -1*Double.parseDouble(co[5]);
            double x = -((c*(a*e-b*d)-b*(a*f-d*c))/(a*(a*e-b*d)));
            double y = -(a*f-c*d)/(a*e-b*d);
            String strx = String.format("%4.3f",x);
            String stry = String.format("%4.3f",y);
            System.out.printf(strx+" "+stry);
   	      }
