Read the following SAT test question and then click on a button to select your answer.

If x + (2 times x) is more than y + (2 times y) , then x minus y =

A. negative 5

B. negative (5 over 3)

C. 3 over 5

D. 3 over 5

E.

正确答案:D

解析:

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