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);
		while(sc.hasNextFloat()) {
			float a = sc.nextFloat();
			float b = sc.nextFloat();
			float c = sc.nextFloat();
			float d = sc.nextFloat();
			float e = sc.nextFloat();
			float f = sc.nextFloat();
			float z = a*e - b*d;
			float x = (c * e - f * b)/z;
			float y = (a * f - d * c)/z;
			x = x == -0.0f ? 0.0f : x;
			y = y == -0.0f ? 0.0f : y;
			System.out.printf("%.3f %.3f\n", x, y);
		}
