Solve simultaneous equations using the inverse matrix
The following system is to be solved by using the coefficient inverse
The unknown column is ordered as \(r\) then \(s\)
\[\begin{bmatrix} 6 & 5 \\ 5 & 4 \end{bmatrix}\begin{bmatrix} r \\ s \end{bmatrix} = \begin{bmatrix} 53 \\ 44 \end{bmatrix}\]
