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 Scala (judge verdict: Accepted)

object Main extends App {

  def safeDivide(l: Double, r: Double) = if (l == 0.0) 0.0 else l / r
  def format(x: Double) = {
    val s = (x * 1000).round formatted "%04d"
    s.dropRight(3) + "." + s.takeRight(3)
  }

  val sc = new java.util.Scanner(Console.in)

  while (sc.hasNextLine()) {
    val line = sc.nextLine()
    val Array(a, b, c, d, e, f) = line.split(' ').map(_.toDouble)
    val x = safeDivide(c*e - b*f, a*e - b*d)
    val y = safeDivide(c - a*x, b)

    println(format(x) + " " + format(y))
  }
