4d-5-9d+17
First think of these numbers as separate numbers
4d
-5
-9d
+17
then find the like terms and combine them
4d-9d
and
-5+17
now subtract and add like u would normally do any problem
4d-9d=-5d (remember if the bigger number is negative the answer is gonna be negative.)
-5+17=12
combine both answers
-5d+12
or
12-5d
any one of these two answers will do!
