Set 12: Linear Equations

Choice A is correct. Choice C is the correct answer. 1. Start with the equation: $10x + 10 = 110$ 2. Subtract 10 from both sides: $10x = 110 - 10$ 3. Simplify: $10x = 100$ 4. Divide both sides by 10: $x = \frac{100}{10}$ 5. Simplify: $x = 10$ 6. Verify: $10(10) + 10 = 100 + 10 = 110$ ✓ Choice D is incorrect because this results from adding 10 to 110: $120$, then $120 /10 = 12$. Wrong inverse operation. Choice A is incorrect because this is the value of $10x$. You need to divide by 10. Choice C is incorrect because this results from multiplying 100 by 10: $1000$.
