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;


public class Main{
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		while(sc.hasNextInt()){
			double a = sc.nextInt();
			double b = sc.nextInt();
			double c = sc.nextInt();
			double d = sc.nextInt();
			double e = sc.nextInt();
			double f = sc.nextInt();
			double x, y;
			x = c/a + (-1)*(b/a);
			y = f/e + (-1)*d*x;
			x = (-1*b*y + c)/a;
			x = (int)(x*1000 + 0.5) / (double)1000;
			y = (int)(y*1000 + 0.5) / (double)1000;
			System.out.printf("\f \f",x ,y);
		}
	}
