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;

class Main {


	public static void main(String[] args) throws IOException {

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

		String[] num1 = br.readLine().split(" ");

		Double[] array = new Double[num1.length] ;

		Double x, y =0.0000;

		for(int i=0; i<num1.length; i++){
			array[i] = Double.parseDouble(num1[i]);
		}

		Double tmp = array[3]/array[0];

		array[1] *= tmp;  array[2] *= tmp;

		y = (array[2]-array[5])/(array[1]-array[4]);

		x= (array[5]-array[4]*y)/array[3];

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



/*		Double num = Double.parseDouble(num1);

		System.out.println(String.format("%.3f", num));
*/
	}
