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.*;
public class Main{
  public static void main(String [] args){
    Scanner sc = new Scanner(System.in);
    int a,b,c,d,e,f;
    double x,y;
    while(sc.hasNext()){
      a = sc.nextInt();
      b = sc.nextInt();
      c = sc.nextInt();
      d = sc.nextInt();
      e = sc.nextInt();
      f = sc.nextInt();
      x = 0;
      y = 0;
      try{
        y = (double) (c * d - a * f) / (b * d - a * e);
        x = (double) (c - b * y) / a;
      }catch(Exception ex){
        System.err.println(ex.getMessage());
      }
      System.out.printf("%.3f %.3f\n", x, y);
    }
  }
