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;

public class Program
{
    public static void Main()
    {
        while (true)
        {
            string input = Console.ReadLine();
            if (string.IsNullOrEmpty(input)) break;   //??\?????????????????°??????
            decimal[] num = Array.ConvertAll(input.Split(' '), value => decimal.Parse(value));
            Console.WriteLine(Math.Round((num[2]*num[4]-num[5]*num[1])/(num[4]*num[0]-num[1]*num[3]), 3, MidpointRounding.AwayFromZero).ToString()+" "+(Math.Round((num[2]*num[3]-num[5]*num[0])/(num[1]*num[3]-num[4]*num[0]), 3, MidpointRounding.AwayFromZero)).ToString());
        }
    }
}
