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 C# (judge verdict: Wrong Answer)

using System;


class AOJ
{

    public static void Main()
    {

        while (true)
        {
            string ss = Console.ReadLine();
            if (ss == null) break;

            string[] s = ss.Split(' ');

            int[] a = new int[6];

            for (int i = 0; i < 6; i++)
            {
                a[i] = int.Parse(s[i]);
            }

            double x = (a[2] * a[4] - a[1] * a[5]) / (a[0] * a[4] - a[1] * a[3]);

            double y = (a[0] * a[5] - a[2] * a[3]) / (a[0] * a[4] - a[1] * a[3]);

            Console.WriteLine("{0:##0.000} {1:##0.000}", Math.Round(x, 4, MidpointRounding.AwayFromZero), Math.Round(y, 4, MidpointRounding.AwayFromZero));
        }
    }
