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)

require 'mathn'

STDIN.each_line do |line|
	m = line.split.map(&:to_i).each_slice(3).to_a
	m.reverse! if m[0][0].zero?

	a = m[0][0]
	d = m[1][0]
	1.upto(2) do |i|
		m[0][i] /= a
		m[1][i] -= d * m[0][i]
	end

	y = m[1][2] / m[1][1]
	x = m[0][2] - m[0][1] * y
	puts "%.3f %.3f" % [x, y]
