Set 4: Linear Equations (Intermediate)

Choice B is correct. Choice C is the correct answer. 1. Solve for y: $2y = 12 - 3 x \rightarrow y = 6 - 1.5 x$ 2. Condition: $y > 0 \rightarrow 6 - 1.5 x > 0$ 3. Solve: $6> 1.5 x \rightarrow 4 > x$ 4. Max Integer: Since $x < 4$, max integer is 3. Choice A is incorrect because if x=4, y=0 (not positive). Choice C is incorrect because 2 is valid but not max. Choice D is incorrect because 5 makes y negative.
