I'm not sure how to do this:

\(\displaystyle \dfrac{x\, +\, 5}{2}\, +\, \dfrac{x\, +\, 2}{3}\, =\, 8\)

*I thought about using the LCM of 6 to rid myself of the fractions, but feel myself messing up when it comes to distribution and division/removing fractions.

Thanks! :)

That's a good first step. Multiply everything by 6, and then solve the resulting linear equation. ;)

As stapel said and remember that
\(\displaystyle 6\, \dfrac{x\, +\, 5}{2}\, =\, \dfrac{6}{2}\, (x\, +\, 5)\, =\, 3\, (x\, +\, 5)\)
