Set 14: Linear Equations (Intermediate)

Choice B is correct. Choice B is the correct answer. 1. Subtract 4 x from both sides: $3x - 4 = 11$ 2. Add 4 to both sides: $3x = 15$ 3. Divide by 3: $x = 5$ 4. Verify: $7(5) - 4 = 31$ and $4(5) + 11 = 31$ ✓ Choice C is incorrect because it results from an error in the solution process. Choice D is incorrect because it results from an error in the solution process. Choice C is incorrect because it results from an error in the solution process.
