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;
class test
{
	static void Main()
	{
		string input;
		for ( int j=0; j<2 ; j++ )
		{
			input = Console.ReadLine();
			int[] vv = new int[6];
			string[] ss = new string[6];
			ss = input.Split(' ');

			for ( int i=0; i<6; i++ )
			{
				vv[i] = int.Parse(ss[i]);
			}

			int detA = vv[0] * vv[4] - vv[1] * vv[3];

			double x = (vv[4] * vv[2] - vv[1] * vv[5]) / detA;
			double y = (- vv[3] * vv[2] + vv[0] * vv[5]) / detA;
			
			x = Math.Round( x*1000, MidpointRounding.AwayFromZero ) / 1000;
			y = Math.Round( y*1000, MidpointRounding.AwayFromZero ) / 1000;
			Console.WriteLine("{0:F3} {1:F3}", x, y);
		}
	}
