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;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO 自動生成されたメソッド・スタブ
		doIt();
	}
	public static void doIt(){
		Scanner sc = new Scanner(System.in);
		//a0 1b 2c 3d 4e 5f
		double[] v = new double[6];
		double x = 0;
		double y = 0;
		while(sc.hasNext()){
			boolean bAns = false;
			//System.out.println("ts");
			//Math.round
			for(int i = 0; i < 6; i++){
				v[i] = sc.nextDouble();
				//System.out.println(i + " " + v[i]);
			}
			//sc.nextInt();
			if(v[0] == 0){
				y = v[2] / v[1];
				x = v[5] - v[4]*y;
				x /= v[3];
			}
			else if(v[1] == 0){
				x = v[2] / v[0];
				y = v[5] - v[3]*x;
				y/= v[4];

			else if(v[3] == 0){
				y = v[5] / v[4];
				x = v[2] - v[1]*y;

			else{
				double tmp1 = v[1] * v[3] - v[0] * v[4];

				y = tmp2 / tmp1;

				x = v[2] - v[1]*y;
				x /= v[0];

			}
			//小数点代4位を四捨五入
			y *= 1000;
			y = Math.round(y) / 1000;
			x *= 1000;
			x = Math.round(x) / 1000;
			//System.out.println(x + " " + y);
			System.out.printf("%.3f %.3f\n", x,y);
