1. **Problem:** Determine who is correct in solving the equation $2x + 9 = 3$ between Dexter and Aisha. 2. **Equation:** $2x + 9 = 3$ 3. **Step 1:** Subtract 9 from both sides to isolate the term with $x$. $$2x + 9 - 9 = 3 - 9$$ $$2x = -6$$ 4. **Step 2:** Divide both sides by 2 to solve for $x$. $$\frac{2x}{\cancel{2}} = \frac{-6}{\cancel{2}}$$ $$x = -3$$ 5. **Explanation:** Dexter made a mistake by adding 2 instead of dividing by 2 after subtracting 9. Aisha correctly subtracted 9 and then divided by 2 to find $x = -3$. **Final answer:** Aisha is correct; $x = -3$.
