**Question: 497**

**17.** If 6 – *y* = 2*y* – 6, what is the value of *y* ?

A. 0

B. 2

C. 4

D. 6

E. 12

**Correct Answer:** C

**Explanation:**

**C** To solve for *y*, begin by adding *y* to both sides of the equation, which gives you 6 = 3*y* – 6. Then add 6 to both sides, which gives you 12 = 3*y*. Now divide both sides by 3, and you find that *y* = 4. You can also plug in the answer choices for any question that asks you to solve for a variable: 6 – 4 = 2(4) – 6.
