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 JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

class Main
{

	public static void main(String[] args)throws IOException
	{
		BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
		String str;
		double[] ans=new double[2];
		double det=0;
		while((str=br.readLine())!=null)
		{
			String[] aa=str.split(" ");
			double[] a=new double[aa.length];
			for(int i=0;i<aa.length;i++)
			{
				a[i]=Double.parseDouble(aa[i]);
			}
			det=a[0]*a[4]-a[1]*a[3];
			ans[0]=(a[4]*a[2]-a[1]*a[5])/det;
			ans[1]=(-a[3]*a[2]+a[0]*a[5])/det;
			for(int i=0;i<2;i++)
			{
				if(ans[i]==0){ans[i]=0;}

			}

			System.out.printf("%.3f %.3f\n",ans[0],ans[1]);
