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 NumberFormatException, IOException {
		String			getData;
		BufferedReader 	reader = new BufferedReader(new InputStreamReader(System.in));


		while((getData = reader.readLine()) != null){
			String[]	dataList =getData.split(" ");
			double[]		valueList= new double[dataList.length];

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

			System.out.printf("%.3f %.3f\n", (valueList[2] * valueList[4] - valueList[1] * valueList[5]) / (valueList[0] * valueList[4] - valueList[1] * valueList[3]),
					 (valueList[5] * valueList[0] - valueList[2] * valueList[3]) / (valueList[0] * valueList[4] - valueList[3] * valueList[1]));

		}
