(A) Let $u = \frac{1}{x-1}$ and $v = \frac{1}{y-2}$.Substituting these into the given equations,we get:$5u + v = 2$  --- $(1)$$6u - 3v = 1$ --- $(2)$Multiply equation $(1)$ by $3$ to eliminate $v$:$15u + 3v = 6$ --- $(3)$Adding equation $(2)$ and $(3)$:$(6u - 3v) + (15u + 3v) = 1 + 6$$21u = 7$$u = \frac{7}{21} = \frac{1}{3}$Substitute $u = \frac{1}{3}$ into equation $(1)$:$5(\frac{1}{3}) + v = 2$$v = 2 - \frac{5}{3} = \frac{6-5}{3} = \frac{1}{3}$Now,solve for $x$ and $y$:$\frac{1}{x-1} = \frac{1}{3} \implies x-1 = 3 \implies x = 4$$\frac{1}{y-2} = \frac{1}{3} \implies y-2 = 3 \implies y = 5$Thus,the solution is $(x, y) = (4, 5)$.
