We have a parallelogram.

The diagonals of a parallelogram bisect each other. This means that each diagonal is divided in two equal segments by the other diagonal.

This let us write:


9=2n-1

and


m+8=3m

We can solve for n as:


\begin{gathered} 9=2n-1 \\ 9+1=2n \\ 10=2n \\ n=(10)/(2) \\ n=5 \end{gathered}

and for m as:


\begin{gathered} m+8=3m \\ m-3m=-8 \\ -2m=-8 \\ m=(-8)/(-2) \\ m=4 \end{gathered}

Answer: the value of m is 4.
