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.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = null;
		int[] numList = new int[6];

		try {
			sc = new Scanner(System.in);
			while (sc.hasNext()) {
				//??°???5???????????????(roop)
				for (int i = 0; i < 6; i++) {
					numList[i] = sc.nextInt();
				}

				//X????¨????
				double numX = (numList[2] * numList[4] - numList[1] * numList[5])
						/(numList[0] * numList[4] - numList[1] * numList[3]);
				String X = String.format("%.3f", numX);

				//Y????¨????
				double numY = (numList[5] - numList[3] * numX) / numList[4];
				String Y = String.format("%.3f", numY);

				//???????????????(?°???°?¬¬?????? ?????¨?????\)
				System.out.println(X + " " + Y);
			}

		}catch (Exception e) {
			System.out.println(e);
		} finally {
			if (sc != null) {
				try {
					sc.close();
				} catch (Exception e) {
					// TODO: handle exception
				}
			}
		}
	}
