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.chomp.split.map(&:to_f)
  case
  when a * b * c * d != 0 || d * e != 0
    g = b / e
    h = a / d
    puts sprintf( "%1.3f %1.3f", ( ( c - g * f ) / ( a - g * d ) ), ( ( c - h * f ) / ( b - h * e ) ) )
  when a * b != 0
    g = e / b
    h = d / a
    puts sprintf( "%1.3f %1.3f", ( ( f - g * c ) / ( d - g * a ) ), ( ( f - h * c ) / ( e - h * b ) ) )
  when a == 0
    puts sprintf( "%1.3f %1.3f", f / d, c / b )
  when b == 0
    puts sprintf( "%1.3f %1.3f", c / a, f / e )
  end
