Set 4: Linear Equations (Advanced)

Choice D is correct. Choice C is the correct answer. 1. Multiply by 6 (LCD): $4(x - 5) = 3(x + 1)$ 2. Distribute: $4x - 20 = 3 x + 3$ 3. Subtract 3 x: $x - 20 = 3$ 4. Add 20: $x = 23$ 5. Verify: $2 /3(18)=12$, $1 /2(24)=12$ ✓ Choice C is incorrect because it results from an error in the solution process. Choice B is incorrect because it results from an error in the solution process. Choice A is incorrect because it results from an error in the solution process.
