Cramer's Formula#936
Solve the system of two linear equations with two variables using Cramer's rule.
The system of equations in the example has the form:
It is known that the system always has a unique solution.
The first line contains the coefficients of the first equation, and the second line contains the coefficients of the second equation. All numbers are separated by a space and do not exceed in absolute value.
Print the first root on the first line and the second root on the second line, with an accuracy of .
