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;
import java.math.BigDecimal;

public class Main {

	public static void main(String[] a){

		String str;
		BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));

		try {
			while(null != ( str = bf.readLine() )){
				String[] arr = str.split(" ");
				BigDecimal ansX = new BigDecimal(
						(Integer.parseInt(arr[2]) * Integer.parseInt(arr[4]) - Integer.parseInt(arr[5]) * Integer.parseInt(arr[1])) /
						(Integer.parseInt(arr[0]) * Integer.parseInt(arr[4]) - Integer.parseInt(arr[1]) * Integer.parseInt(arr[3])));
				BigDecimal ansY = new BigDecimal(
						(Integer.parseInt(arr[2]) * Integer.parseInt(arr[3]) - Integer.parseInt(arr[0]) * Integer.parseInt(arr[5])) /
						(Integer.parseInt(arr[1]) * Integer.parseInt(arr[3]) - Integer.parseInt(arr[0]) * Integer.parseInt(arr[4])));
				System.out.println(ansX.setScale(3, BigDecimal.ROUND_HALF_UP) + " " + ansY.setScale(3, BigDecimal.ROUND_HALF_UP));
			}
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try {
