1. **State the problem:** We need to find values of $x$ and $y$ such that lines $l$ and $m$ are parallel. Given angles are $(17x + 14)^\circ$, $(11y + 95)^\circ$, and $(4x - 2)^\circ$ with a transversal $t$.
2. **Identify angle relationships:** Since $l \parallel m$, alternate interior angles are equal. Thus,
$$17x + 14 = 11y + 95$$
3. **Use adjacent angle relationship:** Angles $(11y + 95)^\circ$ and $(4x - 2)^\circ$ are adjacent on line $m$, so they are supplementary:
$$ (11y + 95) + (4x - 2) = 180 $$
4. **Write the system of equations:**
$$\begin{cases} 17x + 14 = 11y + 95 \\ 11y + 95 + 4x - 2 = 180 \end{cases}$$
Simplify second equation:
$$11y + 4x + 93 = 180$$
$$11y + 4x = 87$$
5. **Rewrite first equation:**
$$17x + 14 = 11y + 95$$
$$17x - 11y = 81$$
6. **Solve the system:**
$$\begin{cases} 17x - 11y = 81 \\ 4x + 11y = 87 \end{cases}$$
Add equations to eliminate $y$:
$$ (17x - 11y) + (4x + 11y) = 81 + 87 $$
$$ 21x = 168 $$
$$ x = \frac{168}{21} = 8 $$
7. **Find $y$ by substituting $x=8$ into second equation:**
$$4(8) + 11y = 87$$
$$32 + 11y = 87$$
$$11y = 87 - 32 = 55$$
$$y = \frac{55}{11} = 5$$
**Final answer:**
$$x = 8, \quad y = 5$$
