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.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {
    public static void main(String[] args) throws Exception {
        // Here your code !
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String readBuffer;
        while( (readBuffer = br.readLine()) != null) {
            String[] line = readBuffer.split(" ");
            int a = Integer.parseInt(line[0]);
            int b = Integer.parseInt(line[1]);
            int c = Integer.parseInt(line[2]);
            int d = Integer.parseInt(line[3]);
            int e = Integer.parseInt(line[4]);
            int f = Integer.parseInt(line[5]);
            double[] ans = equation(a,b,c,d,e,f);
            System.out.println(ans[0] + " " + ans[1]);
        }
        
    }
    //return double[0];x double[1]:y
    static double[] equation(int a,int b,int c,int d,int e,int f){
        double[] ans = new double[2];
        ans[0] = (c * e - b * f) / (a * e - b * d);
        ans[1] = (f * a - c * d) / (a * e - d * b);
        return ans;
