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.Scanner;


public class Main {
	public static void main(String[] args){
		Scanner scan = new Scanner(System.in);
		int a = 0;
		int b = 0;
		int c = 0;
		int d = 0;
		int e = 0;
		int f = 0;

		double x=0,y=0;

		while(scan.hasNextInt()){
			a = scan.nextInt();
			b = scan.nextInt();
			c = scan.nextInt();
			d = scan.nextInt();
			e = scan.nextInt();
			f = scan.nextInt();

			double det = (double)(d*b - a*e);

			y = (double)(d*c-a*f)/det;
			x = (double)(c-b*y)/a;

			System.out.printf("%.3f %.3f\n", x, y);
		}
