Start with 
. That gives 
. Write the ones' place down underneath the 
and the 
and carry the 
to the next place.
Next, do 
. That gives 
. However, remember to add the 
you carried over from the previous step.
Now, write down 
down next to the 
. Make sure the 
is lined up beneath the 
and 
and the 
is in the hundreds' place.
Now, do 
. Because we are multiplying using the tens' place of 
, you need to make sure that you write down the product of 
and 
in the tens' place, underneath the 
from your previous answer.
Next, do 
. Write this product (
) in the hundreds' place.
Finally, add these two numbers together.

To solve for m we need to isolate m on one side of the equation and all other numbers on the other side of the equation.
Our first step is to divide by 12 on both sides. Remember to undo an operation from one side of the equation and cancel out a number we need to perform the opposite operation. If you have a number multiplied by another number or a variable you need to divide to cancel out that said number.
Then we divide by 3 to get our final answer.
