  <statement>
    <p>
          Explain how to use convolution along with the formula
          <m>\mathcal{L}\{e^{at})=\frac{1}{s-a}</m>to find the following
          inverse Laplace transform:
      </p>
    <me>
          \mathcal{L}^{-1}\left\{ \frac{3}{5 \, {\left(s + 7\right)} {\left(s - 4\right)}} \right\}
      </me>
  </statement>
  <answer>
    <me> \frac{3}{55} \, e^{\left(4 \, t\right)} - \frac{3}{55} \, e^{\left(-7 \, t\right)} </me>
