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 {
    def main(args: Array[String]) = {
        val in = io.Source.stdin.getLines.map(_.split(" ").map(_.toDouble))
        in.foreach(x => println("%.3f %.3f".format((x(2)*x(4)-x(1)*x(5))/(x(0)*x(4)-x(1)*x(3))+0, (x(0)*x(5)-x(2)*x(3))/(x(0)*x(4)-x(1)*x(3))+0)))
    }
}
