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)

public class Hello{
    public static void Main(){
        string line = System.Console.ReadLine();
        while(line != null)
        {
            string[] n = line.Split(' ');
            decimal a = decimal.Parse(n[0]);
            decimal b = decimal.Parse(n[1]);
            decimal c = decimal.Parse(n[2]);
            decimal d = decimal.Parse(n[3]);
            decimal e = decimal.Parse(n[4]);
            decimal f = decimal.Parse(n[5]);
             
            decimal x = (c * e - b * f) / (a * e - b * d);
            decimal y = (c * d - a * f) / (b * d - a * e);
             
            System.Console.WriteLine(x.ToString("0.000") + " " + y.ToString("0.000"));
            line = System.Console.ReadLine();
        }
    }
