To rewrite the equation \( \frac{5}{2}x - 8 - 1 = 9 \) as two equations joined by "and," we can first simplify the equation.

Starting with:

\[ \frac{5}{2}x - 8 - 1 = 9 \]

We simplify it to:

\[ \frac{5}{2}x - 9 = 9 \]

Next, we can isolate \( \frac{5}{2}x \):

\[ \frac{5}{2}x = 9 + 9 \]

This leads to:

\[ \frac{5}{2}x = 18 \]

From here, we can express the solution. Multiplying both sides by \( \frac{2}{5} \) gives:

\[ x = \frac{18 \cdot 2}{5} = \frac{36}{5} \]

Now, our rewritten equation becomes:

\[ \frac{5}{2}x - 9 = 9 \quad \text{and} \quad x \neq -4 \]

However, among the provided responses, the correct reformulation of the original equation can accurately appear in the form of:

\[ \frac{5}{2}x - 8 - 1 = 9 \quad \text{and} \quad x \neq -4 \]

Thus, the best response from your options is:

52x−8−1=9 and x≠−4
