D) #(x,2x)# is the most accurate.

Explanation:

A is just one of the many solutions, not a general form.

B is wrong, since the resulting equation, #3/2x=0#, is true only for #x=0#.

C seems right, but as it is presented, it seems as if it's implying that any #x,y# are solutions to the equation which is wrong. It can be made right if the constraint #y=2x# is added.

D is the most accurate because for any #x#, #2x-2x=0#.
