Hi Nathaniel,
$\displaystyle \frac{2k-3}{6}-\frac{3k+1}{8}$
The GCF is 24.
Multiply each term by 24 and place the result over 24.
$\displaystyle \frac{24\left(\frac{2k-3}{6}\right)-24\left(\frac{3k+1}{8}\right)}{24}$
$\displaystyle \frac{4(2k-3)-3(3k+1)}{24}$
$\displaystyle \frac{8k-12-9k-3}{24}$
$\displaystyle \frac{-k-15}{24}$
$\displaystyle \frac{-(k+15)}{24}$
