Question

-4(d+5)-3d>8 ?

Answer 1

first distribute the -4 into the parenthesis to get
-4d-20

so now you have
-4d-20-3d > 8, combine like terms to get -7d-20>8, add 20 to both sides to get
-7d>28, divide both sides by -7, note that when dividing by a negative, the direction of the sign should change so you get
d<-4
