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.IOException;
import java.io.InputStreamReader;


public class Main {
	public static void main(String[] args) throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String str;
		String strArray[];
		double n[] = new double[6];
		double det,x=0,y=0;

		while((str=br.readLine()) != null){
			strArray = str.split(" ");

			for(int i=0; i<6; i++){
				n[i] = Double.parseDouble(strArray[i]);
			}

			det = n[1]*n[3] - n[0]*n[4];
			x = (n[1]*n[5] - n[4]*n[2])/det;
			y = (n[2]-n[0]*x)/n[1];

			if(x == -0){
				x = x * -1;
			}

			if(y == -1){
				y = y * -1;
			}

			System.out.println(String.format("%.3f", x) + " " + String.format("%.3f", y));

		}
	}
