The correct answer is D

Explanation

The statement given in words translates into the equation x plus (2 times y) equals y plus (2 times y) plus 5. This simplifies to 3 times x equals (3 times y) plus 5. Then (3 times x ) minus (3 times y) equals 5, and so 3 times (x minus y) equals 5.
It follows that x minus y equals (5 over 3).
