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 C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main(void) {

	double a=0,b=0,c=0,d=0,e=0,f=0;
	
	while(1){
		scanf("%lf %lf %lf %lf %lf %lf", &a, &b, &c, &d, &e, &f);
		
		double m=a*e -b*d;
		double x= (c*e-b*f)/m;
		double y=(a*f-c*d)/m;
		
		printf("%.3f %.3f\n", x, y );
	
	}
	
	return 0;
