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;

class Main {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);

        while (sc.hasNextInt()) {
            double a1 = sc.nextInt();
            double b1 = sc.nextInt();
            double c1 = sc.nextInt();
            double a2 = sc.nextInt();
            double b2 = sc.nextInt();
            double c2 = sc.nextInt();

            double a = (a1*b2 - a2*b1);
            double x = (c1*b2 - c2*b1) / a + 0;
            double y = (a1*c2 - a2*c1) / a + 0;
            System.out.printf("%.3f %.3f\n", x, y);
        }
    }
