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)

lines=readlines.to_a
lines.each do |line|
  a,b,c,d,e,f=line.split.map(&:to_i)

  if a != d
    a_dush = a * d
    b *= d
    c *= d
    d *= a
    e *= a
    f *= a
    a = a_dush
  end
  b_dush = b - e
  c_dush = c - f
  y = c_dush / b_dush.to_f
  x = (c - b * y) / a.to_f
  if x == -0.000
    x = 0.000
  elsif
    y == -0.000
    y = 0.000
  end

  puts sprintf("%.3f",x) + " " + sprintf("%.3f",y)
end
