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: Wrong Answer)

import java.util.Scanner;
import java.math.*;

public class Main {

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);

		while (true) {
			int[] number = new int[6];
			double x,y;
			if(in.hasNextInt()==false){
				break;	
			}
			
			for(int i =0; i<6; i++){
				number[i] = in.nextInt();
			}
			y = ((number[2]*number[3]-number[5]*number[0])/(number[1]*number[3]-number[0]*number[4])) + 0.0;
			x = ((number[2]-number[1]*y)/number[0]) + 0.0;
			BigDecimal bi = new BigDecimal(String.valueOf(x));
			BigDecimal bi2 = new BigDecimal(String.valueOf(y));
			System.out.print(bi.setScale(3, BigDecimal.ROUND_HALF_UP)+" ");
			System.out.println(bi2.setScale(3, BigDecimal.ROUND_HALF_UP));
		}
		in.close();
