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)

class Simultaneous
  def initialize(array)
    @formula1 = array.slice(0, 3)
    @formula2 = array.slice(3, 3)
  end

  attr_accessor :formula1, :formula2

  def calc
    x = (@formula1[2] * @formula2[1] - @formula1[1] * @formula2[2]) / (@formula1[0] * @formula2[1] - @formula1[1] * @formula2[0]).to_f
    y = (@formula1[2] * @formula2[0] - @formula1[0] * @formula2[2]) / (@formula1[1] * @formula1[0] - @formula1[0] * @formula2[1]).to_f
    return sprintf("%.3f %.3f", x, y)
  end
end

while data = gets
  puts Simultaneous.new(data.split(" ").map(&:to_i)).calc
end
