Choice Ahoice D is the correct answer. This equation involves the distributive property.

1. Start with the equation: $2(x + 3) = 14$
2. Distribute the 2: $2x + 6 = 14$
3. Subtract 6 from both sides: $2x = 14 - 6$
4. Simplify: $2x = 8$
5. Divide by 2: $x = 4$
6. Verify: $2(4 + 3) = 2(7) = 14$ ✓

💡 Alternative Method: You could also divide by 2 first: $x + 3 = 7$, then $x = 4$.

Choice Ahoice B is incorrect because this results from adding 3 to 14? Or maybe $2x = 20$? Common error.

Choice Ahoice D is incorrect because this results from distributing incorrectly as $2x + 3 = 14$, then $2x = 11$, $x=5.5$? Or maybe $2x+6=16$?

Choice Ahoice C is incorrect because this results from subtracting 3 from 14: $11$.
