=# -8d +3w#

Explanation:

We can simplify this by using two different concepts.

No. 1. Subtraction is the same as ADDING on the INVERSE.
To find the inverse of a term, change the sign,

#-(8d -3w) = + (-8d+ 3w)#

=# -8d +3w#

No. 2. Using the multiplication of negative signs:
"multiplying by a negative changes the signs"

#-(8d -3w) = + (-8d+ 3w)#

=# -8d +3w#
