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
	num = line.split().map(&:to_i)
	a = num[0]
	b = num[1]
	c = num[2]
	d = num[3]
	e = num[4]
	f = num[5]
	# p num
	x = ((b * f) - (e * c))/((b * d) - (e * a))
	y = (c - a*x)/b
	puts printf("%1.00000f %1.00000f", x.to_f, y.to_f)
	# puts "#{x} #{y}"
end
