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
  a, b, c, d, e, f = line.split.map(&:to_f)
  boo = a * d
  if boo == d
    bb = (boo / a) * b
    cc = (boo / a) * c
    ee = (boo / d) * e
    ff = (boo / d) * f
    x = bb - ee
    w = cc - ff
    v = w / x
    an = c - b * v
    ans = an / a
    printf("%.3f %.3f\n", ans, v)
  elsif boo == a
    bb = (boo / a) * b
    cc = (boo / a) * c
    ee = (boo / d) * e
    ff = (boo / d) * f
    x = bb - ee
    w = cc - ff
    v = w / x
    an = c - b * v
    ans = an / a
    printf("%.3f %.3f\n", ans, v)
  else
    bb = (boo / a) * b
    cc = (boo / a) * c
    ee = (boo / d) * e
    ff = (boo / d) * f
    x = bb - ee
    w = cc - ff
    v = w / x
    an = c - b * v
    ans = an / a
    printf("%.3f %.3f\n", ans, v)
  end
