1. **State the problem:**
Solve the equation $$1.5b + 9 = 11$$ and find where Jessie made a mistake.
2. **Step 1: Isolate the term with $$b$$**
Subtract $$9$$ from both sides:
$$1.5b + 9 - 9 = 11 - 9$$
which simplifies to:
$$1.5b = 2$$
Jessie wrote $$1.5b = 3$$, which is incorrect.
3. **Step 2: Solve for $$b$$**
Divide both sides by $$1.5$$:
$$b = \frac{2}{1.5}$$
Simplify the fraction:
$$b = \frac{2}{\cancel{1.5}} \times \frac{\cancel{2}}{1} = \frac{4}{3} \approx 1.333$$
Jessie wrote $$b = 2$$, which is incorrect because the previous step was wrong.
4. **Conclusion:**
Jessie's mistake is in **Step 1** where the subtraction was done incorrectly.
**Final answer:** Jessie made a mistake in Step 1.
