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 static java.lang.Math.*;
public class Main {
	static int a,b,c,d,e,f;
	static Scanner sc = new Scanner(System.in);
	
	static boolean read() {
		if(!sc.hasNextInt()) return false;
		a = sc.nextInt();
		b = sc.nextInt();
		c = sc.nextInt();
		d = sc.nextInt();
		e = sc.nextInt();
		f = sc.nextInt();
		return true;
	}
	
	static void solve() {
		int det = a * e - b * d;
		double x, y;
		x =  (double)(c*e - b*f) / det;
		y =  (double)(a*f - c*d) / det;
		x = round(x * 1000) / 1000;
		y = round(y * 1000) / 1000;
		System.out.printf("%.3f %.3f\n", x, y);
	}
	
	public static void main(String[] args) {
		while(read()) {
			solve();
		}
	}
