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

				nums[3] = nums[3] * par;
				nums[4] = nums[4] * par;
				nums[5] = nums[5] * par;
				var y = (nums[2] - nums[5]) / (nums[1] - nums[4]);
				var x = (nums[2] - nums[1] * y) / nums[0];
				var resultX = ToHalfAdjust(x, 3);
				var resultY = ToHalfAdjust(y, 3);
				Console.WriteLine("{0:F3} {1:F3}", resultX, resultY);

			double dCoef = System.Math.Pow(10, iDigits);

			return dValue > 0 ? System.Math.Floor((dValue * dCoef) + 0.5) / dCoef :
								System.Math.Ceiling((dValue * dCoef) - 0.5) / dCoef;
