you compare like terms first
1.5n add it to 2n
it will equal to 1.7
then add 16.5 to 12
it will equal to 28.5
Your new equation will be
1.7n+ 28.5 if it was equal to something let's say it was equal to 180 as an example:
your equation will be
1.7n + 28.5= 180
-28.5= -28.5
1.7n= 151.5 you would divide it
it would equal 89.1 and change.
