![### Applying the Inverse Laplace Transform
To solve for \( y \), we apply the inverse Laplace transform \( \mathcal{L}^{-1} \) to each term of \( \mathcal{L}\{y\} \). Doing so gives the following result. We then use linearity to rewrite the terms on the right side of the equation.
\[
\mathcal{L}\{y\} = \frac{1}{36} \left( \frac{1}{s} \right) - \frac{18}{35} \left( \frac{1}{s-1} \right) + \frac{823}{360} \left( \frac{1}{s-6} \right) - \frac{403}{504} \left( \frac{1}{s+6} \right)
\]
\[
y(t) = \mathcal{L}^{-1} \left\{ \frac{1}{36} \left( \frac{1}{s} \right) - \mathcal{L}^{-1} \left\{ \frac{18}{35} \left( \frac{1}{s-1} \right) + \mathcal{L}^{-1} \left\{ \frac{823}{360} \left( \frac{1}{s-6} \right) - \mathcal{L}^{-1} \left\{ \frac{403}{504} \left( \frac{1}{s+6} \right) \right\} \right\} \right\}
\]
Breaking it down using linearity:
\[
= \frac{1}{36} \mathcal{L}^{-1} \left\{ \frac{1}{s} \right\} - \frac{18}{35} \mathcal{L}^{-1} \left\{ \frac{1}{s-1} \right\} + \frac{823}{360} \mathcal{L}^{-1} \left\{ \frac{1}{s-6} \right\} - \frac{403}{504} \mathcal{L}^{-1} \left\{ \frac{1}{s+6} \right\}
\]
