Answer:

m=  -2

Step-by-step explanation:

simplify and solve

9m-12-3m=2m-18+m

6m-12=3m-18

3m=-6

m=-2

Answer:

m=-2

Step-by-step explanation:

3(3m-4)-3m=2m-18+m

remove the parentheses and collect like terms

9m-12-3m=3m-18

collect the terms

6m-12=3m-18

move the terms

6m-3m=-18+12

collect like terms and add them

3m=-6

Divide both sides by 3

m=-2
