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 Python3 (judge verdict: Accepted)

while 1:
  try:
    s=list(map(float,input().split()))
    up=s[4]/s[1]
    a=s[0]*up
    b=s[1]*up
    c=s[2]*up
    d=s[3]
    e=s[4]
    f=s[5]
  
    ad=a-d
    cf=c-f
    x=round(cf/ad,3)
    if x==-0.000:
      x=0.00
    y=round((s[2] - s[0]*x)/s[1],3)
    if y==-0.000:
      y=0.000
    print('{:.3f}'.format(x),'{:.3f}'.format(y))

  except EOFError:
    break
