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)

while io = gets
  a,b,c,d,e,f = io.split(" ").map(&:to_f)
  delta = a*e-b*d
  x = ((e*c-b*f)/delta).round(3)
  y = (a*f-c*d)/delta.round(3)
  if x == 0
    x = 0.000
  end
  if y == 0
    y = 0.000
  end
  puts "#{sprintf("%.3f", x)} #{sprintf("%.3f", y)}"
end
