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
