Quote:
(x-2)(y-3)=6?

(1) 3x=y(x-2)

(2) (x-8)(y^2+5) =0

-> (1)
(x-2)(y-3)=6 -> y*(x-2)-3*(x-2)=6
= 3x=y(x-2) -> 3x-3*x+6=6
sufficient.

-> (2) (x-8)(y^2+5) =0
x-> 8
y-> not possible. we can not determine y nor can we substitute something in our original equation. we can not prove the given equation = 6.

can someone confirm?

If x and y are positive, does (x-2)(y-3)=6?

(1) 3x=y(x-2)

(2) (x-8)(y^2+5) =0

Kudos for a correct solution.

The correct answer is A.
