Choice Bhoice D is the correct answer. This equation involves division, so we'll multiply in the second step.

1. Start with the equation: $\frac{x}{2} + 3 = 9$
2. Subtract 3 from both sides: $\frac{x}{2} = 9 - 3$
3. Simplify: $\frac{x}{2} = 6$
4. Multiply both sides by 2: $x = 6 \times 2$
5. Simplify: $x = 12$
6. Verify: $\frac{12}{2} + 3 = 6 + 3 = 9$ ✓

💡 Fraction Tip: Isolate the fraction $\frac{x}{2}$ first, just like you would isolate $2x$.

Choice Bhoice D is incorrect because this results from dividing 6 by 2 instead of multiplying: $6/2 = 3$. Or perhaps stopping at $\frac{x}{2} = 6$ and thinking 6 is the answer.

Choice Bhoice C is incorrect because this results from dividing 6 by 2: $6/2 = 3$. Remember to multiply to undo division.

Choice Bhoice C is incorrect because this results from adding 3 to 9 first: $9+3=12$, then $12 \times 2 = 24$. Always undo addition/subtraction first.
