Solve System of Linear Equations (2 Unknowns)

A system of linear equations is common in daily life. The system of linear equations is simply a set of multiple linear questions. For example, if we have two unknown variables, x_1 and x_2.

The typical system of linear equations is

    \begin{eqnarray*}a_{11}x_1+a_{12}x_2=b_1\\a_{21}x_1+a_{22}x_2=b_2\end{eqnarray*}

where a_{11}, a_{12}, a_{21}, a_{22} are coefficients, and b_1 and b_2 are constants.
