Set 3: Linear Equations (Advanced)

Choice B is correct. Choice Ahoice D is the correct answer. 1. Start with the equation: $2(4 x + 2) = 20$ 2. Distribute: $8x + 4 = 20$ 3. Subtract 4: $8x = 16$ 4. Divide by 8: $x = 2$ 5. Verify: $2(4(2) + 2) = 2(10) = 20$ ✓ Choice Ahoice B is incorrect because it results from an error in the solution process. Choice Ahoice D is incorrect because it results from an error in the solution process. Choice Ahoice C is incorrect because it results from an error in the solution process.
