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)

a = 0
while line = STDIN.gets
	if a != 0 then
		print("\n")
	end

	if(/exit/ =~ line)
		break
	end
	temp = line.scan(/\d+|-\d+/)
	a = temp[0].to_i
	b = temp[1].to_i
	c = temp[2].to_i
	d = temp[3].to_i
	e = temp[4].to_i
	f = temp[5].to_i
	x = (c*e-b*f)/(a*e-b*d)
	y = (c*d-f*a)/(b*d-e*a)
	print sprintf("%.3f %.3f",x,y)
	a += 1
end
