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: Accepted)

module Input
	def numread()
		s = gets().split()
		p = Array.new()
		for i in 0...s.size()
			p[i] = s[i].to_i()
		end
		return p
	end
	
	module_function:numread
end

include Input

loop{
	if(STDIN.eof())
		break
	end
	w = numread()
	x = (w[2] * w[4] - w[1] * w[5]).to_f / (w[0] * w[4] - w[1] * w[3]) + 0.00001
	y = (w[2] * w[3] - w[0] * w[5]).to_f / (w[1] * w[3] - w[0] * w[4]) + 0.00001
	print(sprintf("%.3f %.3f\n",x,y))
}
