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.math.BigDecimal;
import java.util.Scanner;

   class Main{

    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);

        double a = scan.nextDouble();
        double b = scan.nextDouble();
        double c = scan.nextDouble();
        double d = scan.nextDouble();
        double e = scan.nextDouble();
        double f = scan.nextDouble();

        double y = (c * d - a * f) / (b * d - a * e);

        double x = (c - b * y) / a;
        BigDecimal big1 = new BigDecimal(y);
        BigDecimal big2 = new BigDecimal(x);

        BigDecimal bigY = big1.setScale(3, BigDecimal.ROUND_HALF_UP);
        BigDecimal bigX = big2.setScale(3, BigDecimal.ROUND_HALF_UP);

        System.out.println(bigX + " " + bigY);

        scan.close();

    }
