  <statement>
    <p>Explain how to find the particular solution to each given IVP.</p>
    <ol>
      <li>
        <me> 0 = {x''} + 4 \, {x} \hspace{2em}
           {x} (0)= 3 ,
           {x} '(0)= -8 </me>

      <li>
        <me> 7 \, {y'} = {y''} + 10 \, {y} \hspace{2em}
           {y} (0)= -3 ,
           {y} '(0)= -3 </me>
      </li>
    </ol>
  </statement>
  <answer>
    <me> {x} = 3 \, \cos\left(2 \, t\right) - 4 \, \sin\left(2 \, t\right) </me>
    <me> {y} = e^{\left(5 \, t\right)} - 4 \, e^{\left(2 \, t\right)} </me>
