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)

function Main(input) {
    lines=input.split("\n");
    for(var i in lines){
	if(lines[i]==" ")break;
	a=lines[i].split(" ").map(function(x){return parseFloat(x);});
	x=Math.round((a[4]*a[2]-a[1]*a[5])/(a[0]*a[4]-a[1]*a[3])*1000)/1000;
	y=Math.round((a[0]*a[5]-a[3]*a[2])/(a[0]*a[4]-a[1]*a[3])*1000)/1000;
	console.log("%f %f",x.toFixed(3),y.toFixed(3));
    }
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
