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)

values = gets
a,b,c,d,e,f = values.split(' ').map{|i| i.to_f}
if a == 0
 y = (c/b)
 x = ((f-e*y)/d)
elsif b == 0
 x = (c/a)
 y = ((f-d*x)/e)
elsif d == 0
 y = (f/e)
 x = ((c-b*y)/a)
elsif e == 0
 x = (f/d)
 y = ((c-a*x)/b)
else
 x = ((b*f-c*e)/(b*d-a*e))
 y = ((c-a*x)/b)
end


if x == 0
  x = x.to_s.delete("-").to_f
end

if y == 0
  y = y.to_s.delete("-").to_f
end

puts "#{sprintf("%.3f",x.round(3))} #{sprintf("%.3f",y.round(3))}"
