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)

x=require('fs').readFileSync('/dev/stdin','utf8').split(/\n/);
for(j = 0;j < x.length;j++){
y=x[j].split(/\s/);
stack = new Array();
for (i = 0; i < y.length; i++) {
        c=y[i];
         switch (c) {
            case '+': stack.push(  stack.pop() + stack.pop()); break;
            case '-': stack.push( -stack.pop() + stack.pop()); break;
            case '*': stack.push(  stack.pop() * stack.pop()); break;
            case '/': stack.push(1/stack.pop() * stack.pop()); break;
            default:  stack.push(isNaN(c) ? 0:parseFloat(c));
        }
}
console.log(stack[0].toFixed(6));
}
