First eq: log₂(x-y) = 1 ⇒ x - y = 2. Second eq: log₃x = (log₃y)/(log₃9) = (log₃y)/2 ⇒ 2log₃x = log₃y ⇒ log₃x² = log₃y ⇒ x² = y. Substituting: x² - x - 2 = 0 ⇒ (x-2)(x+1)=0 ⇒ x=2 or x=-1 ⇒ y=4 or y=1. Check x-y=2: For (2,4): 2-4=-2 ≠2; For (-1,1): -1-1=-2≠2. Neither satisfies x-y=2. So no real solution.
