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) {
		
		@SuppressWarnings("resource")
		Scanner ab = new Scanner(System.in);
		
		while(ab.hasNext())
		{
		
		double a = ab.nextDouble();
		
		double b = ab.nextDouble();
		
		double c = ab.nextDouble();
		
		double d = ab.nextDouble();
		
		double e = ab.nextDouble();
		
		double f = ab.nextDouble();
		
		double x = (c*e - f*b)/ (a*e - b*d);
		
		double y = (c - a*x)/b;
		
		if( x == 0 || x == -0 ) x = 0;
		if( y == 0 || y == -0 ) y = 0;
		
		System.out.printf("%.3f %.3f\n",x,y);
		
		
		
		}
	}
