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.math.BigDecimal;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        while(sc.hasNext()){
            double a = sc.nextDouble();
            double b = sc.nextDouble();
            double c = sc.nextDouble();
            double d = sc.nextDouble();
            double e = sc.nextDouble();
            double f = sc.nextDouble();
            double resultX = (c * e - b * f) / (a * e - b * d);
            double resultY =  (c - a * resultX) / b;
            BigDecimal x = new BigDecimal(resultX).setScale(3, BigDecimal.ROUND_HALF_UP);
            BigDecimal y = new BigDecimal(resultY).setScale(3, BigDecimal.ROUND_HALF_UP);
            System.out.println(x + " " + y);
        }
    }
