How do I simplify this?
3 over 4 + 2 over 3(s + 2t) + s
$\displaystyle = \frac{3}
{4} + \frac{2}
{3}\left( {s + 2t} \right) + s \hfill \\$
$\displaystyle = \frac{3}
{4} + \frac{2}
{3}s + \frac{4}
{3}t + \frac{3}
{3}s \hfill \\$
$\displaystyle
= \frac{3}
{4} + \left( {\frac{2}
{3}s + \frac{3}
{3}s} \right) + \frac{4}
{3}t \hfill \\$
$\displaystyle = \frac{3}
{4} + \frac{5}
{3}s + \frac{4}
{3}t \hfill \\ $
