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.io.*;

public class Main {
	public static void main(String[] args) throws IOException {
		BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		String s;
		while(null != (s = in.readLine())){
			String[] arr = s.split(" ",0);
			double[] iarr = toDoubleArray(arr);
			calc(iarr);
		}
	}
	private static double[] toDoubleArray(String[] arr){
		double[] result = new double[arr.length];
		for(int i=0;i<arr.length;i++)
			result[i] = Integer.parseInt(arr[i]);
		return result;
	}
	private static void calc(double[] arr){
		double det = arr[0]*arr[4]-arr[1]*arr[3];
		double x = (arr[2]*arr[4]-arr[1]*arr[5])/det;
		double y = (-arr[2]*arr[3]+arr[0]*arr[5])/det;
		if(x==-0)x=0.0;
		if(y==-0)y=0.0;
		System.out.printf("%.3f %.3f\n",x,y);
	}
