Answer:

[tex]m = - 1[/tex]

Step-by-step explanation:

[tex]3m - (7m + 12) = 2(m - 3)[/tex]

simplifying bracket first

[tex]3m - 7m - 12 = 2m - 6[/tex]

[tex] - 4m - 12 = 2m - 6[/tex]

grouping like terms

[tex] - 4m - 2m = - 6 + 12[/tex]

[tex] - 6m = 6[/tex]

dividing through by -6

[tex] \frac{ - 6m}{ - 6} = \frac{6}{ - 6} [/tex]

[tex]m = - 1[/tex]
