ok.
200-14d<80
-14d<80-200
-14d<-120
d<-120/-14
if you divide the other side with a negative the sign has to change.
d>-120/-14
d>120/14 (both signs are negative making it positive)
d>60/7 (making it into its simplest form by dividing both by 2 as its is the only                   possibility)
or d>8.57142857143
