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.math.BigDecimal;
import java.util.Scanner;
public class Main {
	public static void main(String[] args){
		Scanner sc=new Scanner(System.in);
		double a=sc.nextInt();
		double b=sc.nextInt();
		double c=sc.nextInt();
		double d=sc.nextInt();
		double e=sc.nextInt();
		double f=sc.nextInt();
		double x=(c*e-b*f)/(a*e-d*b);
		double y=(c-a*x)/b;
		System.out.println(new BigDecimal(x).setScale(3,BigDecimal.ROUND_FLOOR)+" "+new BigDecimal(y).setScale(3,BigDecimal.ROUND_FLOOR));
		sc.close();
	}
