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: Accepted)

using System;

class Class01
{
    public static void Main(string[] args)
    {
        while (true)
        {
            double x, y;
            double[] a = new double[6];
            string s = Console.ReadLine();
            if (s == null) break;
            string[] ss = s.Split();

            for (int i = 0; i < 6; i++)
            {
                a[i] = int.Parse(ss[i]);
            }
            x = (a[1] * a[5] - a[2] * a[4]) / (a[1] * a[3] - a[0] * a[4]);
            y = (a[0] * a[5] - a[2] * a[3]) / (a[0] * a[4] - a[1] * a[3]);

            Console.WriteLine("{0:f3} {1:f3}",Math.Floor(x*1000)/1000,Math.Floor(y*1000)/1000);
        }
    }
