`\begin{cases} \\ \large\bf{\green{ \implies}} \tt \: - \: (1)/(2) \: m \: = \: - 9 \\ \\ \large\bf{\green{ \implies}} \tt \: - (1 \: m)/(2) \: = \: - 9 \\ \\ \large\bf{\green{ \implies}} \tt \: - 1m \: = \: - 9 \: * \: 2 \\ \\ \large\bf{\green{ \implies}} \tt \: - 1m \: = \: - 18 \\ \\ \large\bf{\green{ \implies}} \tt \: m \: = \: ( \cancel- 18)/( \cancel - 1) \\ \\ \large\bf{\green{ \implies}} \tt \: m \: = \: (18)/(1) \\ \\ \large\bf{\green{ \implies}} \tt \: m \: = \: 18 \: \\ \end{cases}`
