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){
	
	int a,b,c,d,e,f;
	double x,y;
	
	for(;;){
	scanf("%d %d %d %d %d %d",&a,&b,&c,&d,&e,&f);
	
	y=(c*d-f*a)/(b*d-e*a);
	x=(c/a)-(b/a)*(c*d-f*a)/(b*d-e*a);
	
	printf("%.3f %.3f",x,y);
	}
