Choice A is the correct answer. Simplify the expression on the left side first.

1. Distribute: $6x - 2 - 4x \leq 10$
2. Combine like terms: $2x - 2 \leq 10$
3. Add 2: $2x \leq 12$
4. Divide by 2: $x \leq 6$

?�� Strategic Tip: Combine $6x$ and $-4x$ carefully to get $2x$.

Choice B is incorrect because it reverses the inequality direction without justification. Choice C is incorrect because it might result from adding 2 to 10 incorrectly (getting 8) or dividing wrong. Choice D is incorrect because it combines wrong value and wrong direction.
