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: Wrong Answer)

using System;

namespace v0_0004
{
    class Program
    {
        static void Main(string[] args)
        {
            string line;
            while (!string.IsNullOrEmpty(line = Console.ReadLine()))
            {
                var input = line.Split(' ');
                int a = int.Parse(input[0]);
                int d = int.Parse(input[3]);

                int b = int.Parse(input[1]) * d;
                int c = int.Parse(input[2]) * d;
                int e = int.Parse(input[4]) * a;
                int f = int.Parse(input[5]) * a;
                b -= e;
                c -= f;
                double y = Math.Round((double)c / b, 3);
                double x = Math.Round((f - y * e) / (a * d), 3);

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