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 Python (judge verdict: Accepted)

import sys

eps = float(pow(10,-7))

while (True):
    L = map(float, sys.stdin.readline().split())
    if L:
        (a, b, c, d, e, f) = L
        x = (e * c - b * f) / (a * e - b * d)
        y = (a * f - d * c) / (a * e - b * d)

        if (abs(x) < eps):
            x = 0.0
        if (abs(y) < eps):
            y = 0.0

        print "{0:.3f} {1:.3f}".format(x, y)

    else:
        break
