Answer:d≥178/23
Step-by-step explanation: Simplify −98+1-98+1−98+1 to −97-97−97.
−23d+81≤−97-23d+81\le -97−23d+81≤−97
2
Subtract 818181 from both sides.
−23d≤−97−81-23d\le -97-81−23d≤−97−81
3
Simplify −97−81-97-81−97−81 to −178-178−178.
−23d≤−178-23d\le -178−23d≤−178
4
Divide both sides by −23-23−23.
d≥−178−23d\ge \frac{-178}{-23}d≥−23−178
5
Two negatives make a positive.
d≥17823d\ge \frac{178}{23}d≥23178
