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)

let input = ''

process.stdin.resume()
process.stdin.setEncoding('utf8')
process.stdin.on('data', function(chunk) {
  input += chunk
})
process.stdin.on('end', function() {
  input = input.split('\n')
  main()
})

function main() {
    for(i=0; i<input.length; i++) {
        input_line = input[i].split(' ')
        // console.log(input_line)
        let sort_input_line = input_line.slice()
        sort_input_line.sort(compareNumbers)
        if (input_line[0] > 1000 || input_line[0] < -1000) {
          return
        }

        let a = input_line[0]
        let b = input_line[1]
        let c = input_line[2]
        let d = input_line[3]
        let e = input_line[4]
        let f = input_line[5]

        let x = (b*f - e*c)/(d*b - a*e)
        let y = (c-a*x)/b
        console.log(x.toFixed(3), y.toFixed(3))
    }
}

function compareNumbers(a, b) {
  return b - a;
}
