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)

if __FILE__ == $0
	while a = gets
		num = []
		num = a.split(nil)
		num = num.map{|n| n.to_f}
		a = num[0]
		b = num[1]
		c = num[2]
		d = num[3]
		e = num[4]
		f = num[5]
		y = (c * d - a * f) / (b * d - a * e)
		x = (c - b * y) / a
		puts "#{sprintf("%.03f", x)} #{sprintf("%.03f", y)}"
	end
