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;
import java.math.BigDecimal;

public class Main{
	static double a,b,c,d,e,f,X,Y;
	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
		while(sc.hasNextInt()){
			a = sc.nextInt();
			b = sc.nextInt();
			c = sc.nextInt();
			d = sc.nextInt();
			e = sc.nextInt();
			f = sc.nextInt();		//1??\?????????????????????????????????
			X = ((((c*e)/b)-f)/(((a*e)/b)-d));
			Y = ((f-((c*d)/a))/(e-((b*d)/a)));
			BigDecimal XX = new BigDecimal(X);
			BigDecimal YY = new BigDecimal(Y);
			BigDecimal XXX = XX.setScale(3, BigDecimal.ROUND_HALF_UP);
			BigDecimal YYY = YY.setScale(3, BigDecimal.ROUND_HALF_UP);
			System.out.println(XXX + " " + YYY);
		}
		sc.close();
	}
