1) 2x + y = 3
2) z = 2
We can start by simplifying the question:
(2xz + yz)/(2xz - y) = ?
z(2x + y)/(2xz - y) = ?
Statement One Alone:
2x + y = 3
Although statement one provides a value for 2x + y, we still do not have a value for z or 2xz -y. Thus, statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.
Statement Two Alone
z = 2
Although statement two provides a value for z, we still do not have a value for 2xz - y or 2x + y. Thus, statement two alone is not sufficient to answer the question. We can eliminate answer choice B.
Statements One and Two Together:
Using statements one and two, we have values for z and 2x + y. However, since we still do not have a value for 2xz - y, we do not have enough information to answer the question.
Answer:
E
