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 JAVA (judge verdict: Accepted)

				//???????????????????¨????
				double x = ( Double.parseDouble(in[4]) * Double.parseDouble(in[2]) - Double.parseDouble(in[1]) * Double.parseDouble(in[5])) / ( Double.parseDouble(in[4]) * Integer.decode(in[0]) - Double.parseDouble(in[1]) * Double.parseDouble(in[3]) );
				double y = ( Double.parseDouble(in[3]) * Double.parseDouble(in[2]) - Double.parseDouble(in[0]) * Double.parseDouble(in[5])) / ( Double.parseDouble(in[3]) * Integer.decode(in[1]) - Double.parseDouble(in[0]) * Double.parseDouble(in[4]) );
				BigDecimal out1 = ( new BigDecimal(x) ).setScale(3, BigDecimal.ROUND_DOWN);
				BigDecimal out2 = ( new BigDecimal(y) ).setScale(3, BigDecimal.ROUND_DOWN);
				System.out.println(out1 + " " + out2);

				line = br.readLine();
