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