It's asking you what you have to do to solve the equation. (How do you get the variable by itself?)
In number 1, you need to "subtract 2m" to get the m's on the same side.
In number 2, you must "subtract 1".
In number 3, you must "add 1".
In number 4, you must "subtract 2".
In number 5, the number of the same side as m is negative, so you must "add 2".
In number 6, you need to "subtract 1". This will leave the m by itself on one side.
Hope this helps!
