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 p0004{
	p0004(){
		string str;
		string[] s;
		double[] a = new double[6];
		double r1, r2, t;
		
		while((str = Console.ReadLine()) != null){
			s = str.Split(' ');
			for(int i = 0; i < 6; ++i)
				a[i] = (double)(int.Parse(s[i]));
			t = a[0]*a[4]-a[1]*a[3];
			r1 = (a[4]*a[2]-a[1]*a[5])/t;
			r2 = (a[0]*a[5]-a[3]*a[2])/t;
			Console.WriteLine("{0} {1}", r1.ToString("f3"), r2.ToString("f3"));
		}

	public static int Main(string[] args){
		new p0004();
		return 0;
	}
