\frac{-t}{2}>\frac{3}{2}<br />

    <br /> <br /> <br />
\frac{-t}{2} * \frac{2}{1}>\frac{3}{2} * \frac{2}{1}<br />

    <br /> <br />
-t>3<br /> <br />

    Then do it just like lonn and Plato showed you: solve it exactly like you would an equation but remember that if you multiply or divide both sides by a negative number, you "reverse" the inequality. I would start by subtracting 7y from both sides.
