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)

#
answer = Array.new

while linebuf = $stdin.gets
		line = linebuf.split( /\s/ )
		line.map!{ |n| n.to_f }
		a = line[ 0 ]; b = line[ 1 ]; c = line[ 2 ] 
		d = line[ 3 ]; e = line[ 4 ]; f = line[ 5 ] 

		di = a * e - b * d
		x1 = e * c - b * f 
		x2 = f * a - c * d
		u1 = x1 / di
		u2 = x2 / di
		answer << [u1,u2]
