A.
Reason: Equivalent equations come from applying the same operation to both sides. A gives (7r)/7 = 15/15, which simplifies to r = 1, while the original gives r = 15/7. Options B, C, and D are obtained by subtracting 9, dividing both sides by 7, and adding 6, respectively, so they are equivalent.
