See full explanation and graph below:

Explanation:

To solve you add #color(red)(6.3)# to each side of the inequality to isolate #x# and keep the inequality balanced:

#-9.1 + color(red)(6.3) < d - 6.3 + color(red)(6.3)#

#-2.8 < d - 0#

#-2.8 < d#

To solve in terms of #d# we reverse or "flip" the inequality:

graph{x > -2.8 [-10, 10, -5, 5]}
