1. **State the problem:** Determine if the two algebraic expressions evaluated with given values are equivalent.
2. **Expressions given:**
- Expression 1: $$\frac{4y}{2} + 4(3x + 3y) - x^3$$ with $x=2$, $y=3$.
- Expression 2: $$6x - y^2 + 3(4 + -5)$$ with $x=8$, $y=3$.
3. **Evaluate Expression 1:**
$$\frac{4y}{2} + 4(3x + 3y) - x^3 = \frac{4 \times 3}{2} + 4(3 \times 2 + 3 \times 3) - 2^3$$
$$= \frac{12}{2} + 4(6 + 9) - 8$$
$$= 6 + 4(15) - 8$$
$$= 6 + 60 - 8$$
$$= 58$$
4. **Evaluate Expression 2:**
$$6x - y^2 + 3(4 + -5) = 6 \times 8 - 3^2 + 3(4 - 5)$$
$$= 48 - 9 + 3(-1)$$
$$= 48 - 9 - 3$$
$$= 36$$
5. **Compare results:**
Expression 1 evaluates to 58.
Expression 2 evaluates to 36.
6. **Conclusion:**
Since $58 \neq 36$, the two expressions are **not equivalent** for the given values of $x$ and $y$.
**Final answer:** The expressions are not equivalent.
