Set 14: Linear Equations

Choice B is correct. Choice Ahoice D is the correct answer. 1. Start with the equation: $6x + 18 = 36$ 2. Subtract 18 from both sides: $6x = 36 - 18$ 3. Simplify: $6x = 18$ 4. Divide both sides by 6: $x = \frac{18}{6}$ 5. Simplify: $x = 3$ 6. Verify: $6(3) + 18 = 18 + 18 = 36$ ✓ Choice Ahoice B is incorrect because this results from adding 18 to 36: $54$, then $54 /6 = 9$. Wrong inverse operation. Choice Ahoice C is incorrect because this is the value of $6x$. You need to divide by 6. Choice Ahoice C is incorrect because this results from multiplying 18 by 6: $108$.
