So you copied this problem down from class?
Did the teacher actually present the problem in words, as you have, or did he/she present it symbolically?

You'll find it much easier to work with a symbolic equation.

Whew!  "After the fraction x plus 1 all over 3 minus the fraction x plus 2 all over 2 x have been combined using the least common denominator of 6x, what is the numerator?"

"fraction x plus 1 all over 3" would be     
(x+1)
-----
    3
Translate the 2nd part of the problem into its symbolic representation.

You end up here with 2 fractions of different denominators that you need to add to gether.  To accomplish this you must determine the lowest common denominator (LCD) and put that denom. to use in your expression.  What is the numerator of the single resultant expression?

tkhunny was asking that you SHOW US YOUR OWN WORK.  I'd surely like to see what you called "the last answer."
