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.util.*;

public class Main {

	/**
	 * @param args

	public static Scanner sc = new Scanner(System.in);
	
	
	void run() {
		int a, b, c, d, e, f;
		double x, y;
		while (sc.hasNextInt()) {
			a = sc.nextInt();
			b = sc.nextInt();
			c = sc.nextInt();
			d = sc.nextInt();
			e = sc.nextInt();
			f = sc.nextInt();
			x = (double)(e*c-b*f)/(a*e-b*d);
			y = (double)(a*f-c*d)/(a*e-b*d);
			if (Math.abs(x) < 10E-5) x = 0.0;
			if (Math.abs(y) < 10E-5) y = 0.0;
			System.out.printf("%.3f %.3f\n",x, y);
		}
