Find the value of "k" in the equation:

$k\left(\begin{array}{cc}3 & -1 \\ 5 & -4\end{array}\right) = \left(\begin{array}{cc}-3/4 & 1/4 \\ -5/4 & 1\end{array}\right)$

do I multiply $3 * (-3/4)$ then $(-1) * 1/4$ then $5 *(-5/4)$ and $(-4) * 1$ ?

    Need to reformat the matrices. I would, but I'm brand new here and don't know how.2012-07-20

    The technique provided in my answer to your other question http://math.stackexchange.com/a/173309/31475 should point you in the right direction.2012-07-20

    It's non-singular, so you can also do this :) $$ k = \left(\begin{array}{cc}-3/4 & 1/4 \\ -5/4 & 1\end{array}\right) \left(\begin{array}{cc}3 & -1 \\ 5 & -4\end{array}\right)^{-1}.$$2012-07-20
