you need to figure out what m is so first subtract 12 from then sybtract 9 from 9 then you havem by itself. now subtract 4 from 4 then add 4m to 4m and the add 15 to 9 and you should get your answer

to get m, you need to have the variable on one side. so subtract 4m from both sides so that the equation is now 8m-9=15.

it is now a two step equation.

add 9 to 15 to get 24 then divide 24 by 8 to get 3.
m=3 is the solution
