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 sc = new Scanner(System.in);
		while(sc.hasNext()) {
			String s = sc.nextLine();
			String []n = s.split(" ");
			double[] v = new double[6];
			for(int i = 0; i < 6; i++) {
				v[i] = Double.parseDouble(n[i]);
			}
			double d = v[0] * v[4] - v[1] * v[3];
			double x = v[4] * v[2] - v[1] * v[5];
			double y = -v[3] * v[2] + v[0] * v[5];
			x /= d;
			y /= d;
			if(x==0)x=0;
            if(y==0)y=0;
			System.out.printf("%.3f %.3f\n", x, y);
		}
		sc.close();
	}
