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 input = gets
  a = input.split.map(&:to_i)
  i = (a[1]*a[5]-a[4]*a[2])/(a[3]*a[1]-a[0]*a[4]).to_f + 0.000
  j = (a[0]*a[5]-a[2]*a[3])/(a[0]*a[4]-a[1]*a[3]).to_f + 0.000
  print sprintf("%.3f",i)
  print "\s"
  puts sprintf("%.3f",j)
end
