1. We are asked to solve the system of linear equations using the elimination method.
Given the first system:
$$\begin{cases} 3x - 2y = 5 \\ 5x - 3y = 8 \end{cases}$$
2. The elimination method involves eliminating one variable by making the coefficients of that variable equal in both equations.
3. Multiply the first equation by 3 and the second equation by 2 to align the coefficients of $y$:
$$\begin{cases} 3(3x - 2y) = 3(5) \\ 2(5x - 3y) = 2(8) \end{cases}$$
which simplifies to
$$\begin{cases} 9x - 6y = 15 \\ 10x - 6y = 16 \end{cases}$$
4. Subtract the first new equation from the second to eliminate $y$:
$$ (10x - 6y) - (9x - 6y) = 16 - 15 $$
which simplifies to
$$ 10x - 6y - 9x + 6y = 1 $$
$$ (10x - 9x) + (-6y + 6y) = 1 $$
$$ x + 0 = 1 $$
$$ x = 1 $$
5. Substitute $x=1$ back into the first original equation:
$$ 3(1) - 2y = 5 $$
$$ 3 - 2y = 5 $$
6. Solve for $y$:
$$ -2y = 5 - 3 $$
$$ -2y = 2 $$
$$ y = \frac{\cancel{-2}y}{\cancel{-2}} = \frac{2}{-2} $$
$$ y = -1 $$
7. Final solution:
$$ \boxed{(x, y) = (1, -1)} $$
