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 Hello{
    public static void Main(){
        string line;
        while((line=Console.ReadLine()) !=null){///// repeat unless no input
            coreProcess(line);
        }
    }
    
    public static void coreProcess(string line){
        string [] input=line.Split(' ');
        double a=int.Parse(input[0]);
        double b=int.Parse(input[1]);
        double c=int.Parse(input[2]);
        double d=int.Parse(input[3]);
        double e=int.Parse(input[4]);
        double f=int.Parse(input[5]);
        
        double y=(a*f-d*c)/(a*e-d*b);
        double x=(c-b*y)/a;
        System.Console.WriteLine("{0:f3} {1:f3}",x, y);
    }
