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: Wrong Answer)

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 m1 = -(b / e);
	d = d * m1;
	e = e * m1;
	f = f * m1;
	var m2 = a + d;
	var x = (c + f) / m2;
	var y = (-a * x + c) / b;
	var xStr = Math.round(x * 1000) + '';
	if (xStr == '0')
		xStr += '000';
	xStr = xStr.replace(/(\d{3})$/, '.$1');
	var yStr = Math.round(y * 1000) + '';
	if (yStr == '0')
		yStr += '000';
	yStr = yStr.replace(/(\d{3})$/, '.$1');

	console.log(xStr + ' ' + yStr);
}
