THE CORRECT ANSWER IS (C). SINCE EITHER STATEMENT CONSIDERED ALONE...

30. The correct answer is (C). Since either statement considered alone involves a linear

equation in two variables, neither statement alone suffices to answer the question.

Consider the two statements together. Notice that, in each equation, the right side is

the same: the number 3. Thus, 5x

2

4y

y.

Given that x

.

0, x must be less than y, and the answer to the question must be no.
