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;

public class Main{

	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		while(scanner.hasNext()) {

			double a = scanner.nextDouble();
			double b = scanner.nextDouble();
			double c = scanner.nextDouble();
			double d = scanner.nextDouble();
			double e = scanner.nextDouble();
			double f = scanner.nextDouble();

			double x = (c*e - f*b)/ (a*e - b*d);
	        double y = (c - a*x)/b;

			if (x == -0) {
				x = 0;
			}
			if (y == -0) {
				y = 0;
			}
			//System.out.println(list);
			System.out.println(String.format("%.3f", x) + " " + String.format("%.3f", y) );
		}
		scanner.close();

	}
