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 Ruby (judge verdict: Wrong Answer)

while (input = STDIN.gets)!=nil do

	if input == "\n"
		break
	end

	data = [0.000,0.000,0.000,0.000,0.000,0.000]
	xy   = [0.000,0.000]

	input = input.split(" ")
	
	for i in 0..5 
		data[i] = input[i].to_f
	end
	
	if input.size != 6
		break
	end
		
	num = (data[0]*data[4]) - (data[1]*data[3])

	xy[0] = ( data[4]    *data[2] + (data[1]*-1)*data[5])/num
	xy[1] = ((data[3]*-1)*data[2] +  data[0]    *data[5])/num
	
	printf "%.3f %.3f\n", xy[0].to_f, xy[1].to_f
