Solve 2x2 Linear System

Problem

Given a $2 \times 2$ matrix $A$ and a vector $b$, solve the linear system $Ax = b$ using Cramer's rule (or direct matrix inversion).

$\begin{pmatrix} a_{11} & a_{12} \\ a_{21} & a_{22} \end{pmatrix} \begin{pmatrix} x_1 \\ x_2 \end{pmatrix} = \begin{pmatrix} b_1 \\ b_2 \end{pmatrix}$

The determinant $\det(A) = a_{11} a_{22} - a_{12} a_{21}$ is guaranteed to be nonzero.

Input Format

Six space-separated values: a11 a12 a21 a22 b1 b2

Output Format

Two space-separated values: x1 x2, each to 4 decimal places.
