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;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                string r = Console.ReadLine();
                if (r == null) break;
                double[] k0 = new double[6];
                 k0[0] = double.Parse(r.Split(' ')[0]);
                 k0[1] = double.Parse(r.Split(' ')[1]);
                 k0[2] = double.Parse(r.Split(' ')[2]);
                 k0[3] = double.Parse(r.Split(' ')[3]);
                 k0[4] = double.Parse(r.Split(' ')[4]);
                 k0[5] = double.Parse(r.Split(' ')[5]);
                string x, y;
                y = ((k0[2] * k0[3] - k0[0] * k0[5]) / (k0[1] * k0[3] - k0[0] * k0[4])).ToString();
                x = ((k0[2] - k0[1] * double.Parse(y)) / (k0[0])).ToString();
                Console.WriteLine(String.Format("{0:0.000} {1:0.000}", double.Parse(x), double.Parse(y)));
            }
        }
    }
