I need help with this pls be nice and tell me the answer :)
KIM [24]

Answer:

m=-10

Step-by-step explanation:

just to make this easier ill subtract 2 from each side to get

2/3m = 1/6m -5

now multiply each side by 6 to get rid of denominators (this just makes it easier)

now in the next steps we simplify

4m = 1m -30

3m= -30

m=-10
