X, Y, and Z are consecutive numbers and X > Y > Z. Also, X + 3Y + 3Z = 5Y + 8. What is the value of Z? Pick one.
A) 2 B) 3 C) 4 D) 5 E) 6
If X, Y, and Z are consecutive numbers and X &gt; Y &gt; Z, then Y = Z+1 and X = Z+2.   X + 3Y + 3Z = 5Y + 8   Z+2+3Z+3+3Z = 5Z+5+8   2Z = 8   Z = 4   The answer is 4.
