See a solution process below:

First, expand the terms within the parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

#8d - color(red)(2)(3d - 5d)#

#8d - (color(red)(2) xx 3d) - (color(red)(2) xx -5d)#

#8d - 6d - (-10d)#

#8d - 6d + 10d#

Now combine the like terms:

#(8 - 6 + 10)d#

#12d#
