  • 2x + 3y = 3
    3x + 5y = 4 

    [tex] \left[\begin{array}{cc}2&3\\3&5\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right][/tex] = [tex] \left[\begin{array}{c}3\\4\end{array}\right][/tex]

    [tex] \left[\begin{array}{c}x\\y\end{array}\right] [/tex] = [tex] \left[\begin{array}{cc}2&3\\3&5\end{array}\right] ^{-1} \left[\begin{array}{c}3\\4\end{array}\right] [/tex]
