Explanation
Choice D is correct. Multiplying both sides of by 5 results in
. Multiplying both sides of
by 2 results in
. Subtracting the resulting equations yields
, which simplifies to
. Dividing both sides of
by
results in
.
Choices A and B are incorrect and may result from incorrectly subtracting the transformed equation. Choice C is incorrect and may result from finding the value of x instead of the value of y.
