Step 1
Subtract 13 from both sides to get:
- 9 < r
That is r > - 9
In general, you can perform any of the following operations on an inequality and preserve its truth:
(1) Add or subtract a value on both sides.
(2) Multiply or divide by a positive value on both sides.
(3) Multiply or divide by a negative value on both sides and reverse the inequality ( < becomes > , becomes , etc).
