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 MyClass
{
    static void Main(string[] args)
    {
        string str = "";
        while ((str = Console.ReadLine()) != null)
        {
            string[] str2 = str.Split(' ');
            int a = int.Parse(str2[0]);
            int b = int.Parse(str2[1]);
            int c = int.Parse(str2[2]);
            int d = int.Parse(str2[3]);
            int e = int.Parse(str2[4]);
            int f = int.Parse(str2[5]);
            Console.WriteLine("{0:0.000} {1:0.000}", Math.Round((double)(c * e - f * b) / (a * e - d * b), 3, MidpointRounding.AwayFromZero), Math.Round((double)(c * d - f * a) / (b * d - e * a), 3, MidpointRounding.AwayFromZero));
        }
    }
