Answer 1

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 0.75}}}}}$

Step-by-step explanation:

$\sf{ - 2m - 5m = 9m - 12}$

Collect like terms

⇒$\sf{ - 7m = 9m - 12}$

Move 9m to left hand side and change it's sign

⇒$\sf{ - 7m - 9m = - 12}$

Collect like terms

⇒$\sf{ - 16m = - 12}$

Divide both sides of the equation by -16

⇒$\sf{ \frac{ - 16m}{ - 16} = \frac{ - 12}{ - 16} }$

Calculate

⇒$\sf{ m = 0.75}$

Hope I helped!

Best regards!!

Answer 2

Answer:

$- 2m - 5m = 9m - 12 \\ ⟶ - 2m - 5m - 9m = - 12 \\ ⟶ - 16m = - 12 \\ ⟶ - m = \frac{ - 12}{16} \\ ⟶ - m = \frac{ - 6}{8} \\ ⟶ m = - ( - \frac{6}{8} ) \\ ⟶m = \frac{6}{8}$

$m=0.75$
