Choice B is the correct answer. I'll use elimination by multiplying first equation by 2.

Step 1: Multiply first by 2: $2x + 4y = 22$

Step 2: Subtract second equation: $(2x + 4y) - (2x + 3y) = 22 - 18$$y = 4$

Step 3: Substitute: $x + 2(4) = 11 \Rightarrow x = 3$

Solution: $(3, 4)$

Verification: $2(3) + 3(4) = 18$ ✓

💡 Strategic Tip: Multiplying first by 2 creates matching $2x$ terms for easy elimination.

Choice A is incorrect because$2(5) + 3(3) = 19 \ eq 18$.

Choice C is incorrect because$2(4) + 3(3.5) = 18.5 \ eq 18$.

Choice D is incorrect because$2(6) + 3(2.5) = 19.5 \ eq 18$.
