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 IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String inData;
        try {
            while ((inData = br.readLine()) != null) {
                String[] abcdefList = inData.split(" ");
                double[] in = new double[6];
                for (int i = 0; i < 6; i++) {
                    in[i] = Double.parseDouble(abcdefList[i]);
                }
                double deno = (in[1] * in[3] - in[0] * in[4]);
                double x = (in[1] * in[5] - in[2] * in[4]) / deno;
                double y = (in[0] * in[5] - in[2] * in[3]) / (deno * -1);
                x = ((int) x == 0) ? 0.0 : x;
                y = ((int) y == 0) ? 0.0 : y;
                System.out.printf("%4.3f %4.3f\n", x, y);
            }
        } catch (Exception e) {
            System.exit(0);
        }
    }
