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 data = gets
  if data==nil then
    break
  end
  data2 = data.split(" ")
  data2.map! {|x| x.to_f}
  x = (data2[5]*data2[1]-data2[2]*data2[4])/(data2[1]*data2[3]-data2[0]*data2[4])

  y = (data2[2]-data2[0]*x)/data2[1]
  puts "#{sprintf("%#.3f",x.round(3))} #{sprintf("%#.3f",y.round(3))}"
end
