I'm assuming you mean (-1/3)m - 7 = 5 (yes there's a difference)
For this, add 7 to both sides
(-1/3)m=12
Multiply both sides by -3
m=-36
(-1/3)m - 7 = 5
or
-1/(3m) - 7 = 5
anyway the steps still the same.
first move (-7) to the other side
it becomes :
(-1/3)m=5+7
then
then multiply both sides by (-3) -the other equation you should multiply by (-3m)
-1/3m= 5+7
<=> -1/3m = 12 ( m different 0)
<=> 12*3m=-1
<=> m= -1/36
-1/3m – 7 = 5......multiply across by 3m
-1 - 21m = 15m
-1 = 36m
m = - 1/36
If you meant -1/(3m – 7) = 5, that's QUITE different. You would get -1 =15m - 35...........
And if you meant (-1/3)m - 7 = 5, that's different again............
multiply the whole thing by -3 to get
m+21= -15
m= -36
brackets would help....depends if it's -(1/3)m or -1/(3m)....
