-23d+81+98d<1
Add 98d to both sides.
75d+81<1
Combine -23d and 98d to get 75d.
75d<1-81
Subtract 81 from both sides.
75d<-80
Subtract 81 from 1 to get -80.
d<\frac{-80}{75}
Divide both sides by 75. Since 75 is positive, the inequality direction remains the same.
d<-\frac{16}{15}
Reduce the fraction \frac{-80}{75} to lowest terms by extracting and canceling out 5.
