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 Program
    {
        static void Main(string[] args)
        {
            string line;
            while (!string.IsNullOrEmpty(line = Console.ReadLine()))
            {
                var input = line.Split(' ');
                var a = double.Parse(input[0]);
                var b = double.Parse(input[1]);
                var c = double.Parse(input[2]);
                var d = double.Parse(input[3]);
                var e = double.Parse(input[4]);
                var f = double.Parse(input[5]);

                double y = Math.Round((c * d - f * a) / (b * d - e * a), 3);
                double x = Math.Round((c - y * b) / a, 3);

                Console.WriteLine("{0:f3} {1:f3}", x, y);
            }
        }
    }
