**Question: 517**

**16.** If 3 more than *x* is 2 more than *y,* what is *x* in terms of *y*?

A. *y* – 5

B. *y* – 1

C. *y* + 1

D. *y* + 5

E. *y* + 6

**Correct Answer:** B

**Explanation:**

**B** Whenever you see variables in the answer choices, you should plug in. Start by plugging in a number for *x*. If *x* = 10, then 3 more than *x* is 13. Now you know that 13 is 2 more than *y*, so *y* = 11. When you plug in 11 for *y* in all of the answers, B is the only one that gives you the answer *x* = 10, your target answer.
