Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{m = 0.75}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 2m - 5m = 9m - 12}[/tex]
Collect like terms
⇒[tex] \sf{ - 7m = 9m - 12}[/tex]
Move 9m to left hand side and change it's sign
⇒[tex] \sf{ - 7m - 9m = - 12}[/tex]
Collect like terms
⇒[tex] \sf{ - 16m = - 12}[/tex]
Divide both sides of the equation by -16
⇒[tex] \sf{ \frac{ - 16m}{ - 16} = \frac{ - 12}{ - 16} }[/tex]
Calculate
⇒[tex] \sf{ m = 0.75}[/tex]
Hope I helped!
Best regards!!
