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)

ARGF.each_line do |line|
  a, b, c, d, e, f = line.split.map(&:to_f)

  if a == 0
    y = c / b
    x = (f - e * y) / d
  elsif b == 0
    x = c / a
    y = (f - d * x) / e
  elsif d == 0
    y = f / e
    x = (c - b * y) / a
  elsif e == 0
    x = f / d
    y = (c - a * x) / b
  end

  unless x || y
    y = ((c / a) - (f / d)) / ((b / a) - (e / d))
    x = (c - b * y) / a
  end

  puts "#{'%1.3f' % x.round(3)} #{'%1.3f' % y.round(3)}"
end
