Set 5: Linear Equations

Choice B is correct. Choice Ahoice D is the correct answer. 1. Start with the equation: $4x - 16 = 0$ 2. Add 16 to both sides: $4x = 0 + 16$ 3. Simplify: $4x = 16$ 4. Divide both sides by 4: $x = \frac{16}{4}$ 5. Simplify: $x = 4$ 6. Verify: $4(4) - 16 = 16 - 16 = 0$ ✓ Choice Ahoice D is incorrect because this might result from thinking $4(-4) = -16$, but $-16 - 16 = -32$, not 0. Choice Ahoice C is incorrect because this is the value of $4x$. You must divide by 4. Choice Ahoice C is incorrect because this results from multiplying 16 by 4: $64$.
