(x-1/x-2)-(x-2/x-3)=(x-4/x-5)-(x-5/x-6)
(x-1/x-2)-(x-4/x-5)=(x-2/x-3)-(x-5/x-6)
[(x-1)(x-5)-(x-4)(x-2)]/[(x-2)(x-5)]=[(x-2)(x-6)-(x-5)(x-3)]/[(x-3)(x-6)]
-3/[(x-2)(x-5)]=-3/[(x-3)(x-6)]
(x-2)(x-5)=(x-3)(x-6)
x²-7x+10=x²-9x+18

(x-1/x-2)-(x-4/x-5)=(x-2/x-3)-(x-5/x-6)
[(x-1)(x-5)-(x-4)(x-2)]/[(x-2)(x-5)]=[(x-2)(x-6)-(x-5)(x-3)]/[(x-3)(x-6)]
-3/[(x-2)(x-5)]=-3/[(x-3)(x-6)]
(x-2)(x-5)=(x-3)(x-6)
