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 JavaScript (judge verdict: Accepted)

var input = require('fs').readFileSync('/dev/stdin', 'utf8');
var lines = input.split('\n');

var line;
while (line = lines.shift()) {
	var vals = line.split(' ').map(function(n){return +n;});
	var a = vals[0];
	var b = vals[1];
	var c = vals[2];
	var d = vals[3];
	var e = vals[4];
	var f = vals[5];

	var D = a * e - b * d;
	var x = (e * c - b * f) / D;
	var y = (a * f - d * c) / D;

	console.log(x.toFixed(3) + ' ' + y.toFixed(3));
