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 java.util.Date;

class Main{
    public static void main(String[] args){
	Scanner sc = new Scanner(System.in);
	int X,Y;
	double  a,b,c,d,e,f,x,y;
	while(sc.hasNext()){
	    a=sc.nextInt();	   
	    b=sc.nextInt();
	    c=sc.nextInt();
	    d=sc.nextInt();
	    e=sc.nextInt();
	    f=sc.nextInt();
	    x=(c*e-b*f)/(a*e-d*b);
	    if(b!=0) y= (c-a*x)/b;
	    else y=(f-d*x)/e;
	    X=(int)(x*1000);
	    Y=(int)(y*1000);
	    x=(double)X/1000;
	    y=(double)Y/1000;
	    System.out.printf("%.3f %.3f",x,y);
	}
    }
