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)

while (line = gets) do
  a, b, c, d, e, f = line.split().map(&:to_f)

  c /= a
  b /= a
  a /= a

  f -= (c * d)
  e -= (b * d)
  d -= (a * d)

  f /= e
  d /= e
  e /= e

  c -= (f * b)
  a -= (d * b)
  b -= (e * b)

  c = (c*(10**4)).round
  c = (c*(10**-4)).round
  f = (f*(10**4)).round
  f = (f*(10**-4)).round

  printf("%.3f %.3f\n", c, f)
end
