## Question

- Find all pairs of values of \(x\) and \(y\) for which
\[\begin{equation*}
\frac{3x+y+1}{8} = \frac{x-y}{5} = \frac{x^2 - y^2}{5}.
\end{equation*}\]
- Solve the equation
\[\begin{equation*}
\sqrt{3-3x} - \sqrt{2-x} = 1.
\end{equation*}\]
*The expression \(\sqrt{u}\) denotes the positive square root of \(u\).*
