Given: y ≠2xzjjjinapinch wrote:If y ≠2xz, what is the value of (2xz + yz)/(2xz - y)?
1) 2x + y = 3
2) z = 2
Official Guide question
Answer: E
To get: Value of (2xz + yz)/(2xz - y)
= (2xz + yz)/(2xz - y) = z(2x + y)/(2xz - y)
Statement 1: 2x + y = 3
=> z(2x + y)/(2xz - y) = 3z/(2xz - y).
We do not have the value of z and (2xz - y). Insufficient.
Statement 1: z = 2
=> z(2x + y)/(2xz - y) = 2(2x + y)/(4x - y).
We do not have the value of (2x + y) and (4x - y). Insufficient.
Statement 1 & 2:
z(2x + y)/(2xz - y) = 2*3/(4x - y) = 6/(4x - y).
We do not have the value of (4x - y). Insufficient.
The correct answer: E
Hope this helps!

We can start by simplifying the question:jjjinapinch wrote:If y ≠2xz, what is the value of (2xz + yz)/(2xz - y)?
1) 2x + y = 3
2) z = 2
(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.
