So, we have to get the value of y/x.

Looking at statement 1, we see that y/x = 3; however, this is incorrect. For the answer to be choice A, the question should have defined that x is a nonzero number, but it didn't. So, we must ensure whether x is a nonzero number. Statement 2 defines it, so it is also needed. y/x = 3. The correct answer is C.

Correct answer: C

Hope this helps!
