#### Answer

$t=9$

#### Work Step by Step

Using properties of equality, the solution to the given equation, $
-\dfrac{4}{3}t=-12
$, is
\begin{array}{l}\require{cancel}
-\dfrac{3}{4}\left(-\dfrac{4}{3}t\right)=-12\left(-\dfrac{3}{4}\right)
\\\\
\dfrac{12}{12}t=-3\cdot\cancel{4}\left(-\dfrac{3}{\cancel{4}}\right)
\\\\
t=9
.\end{array}
