Choice B is the correct answer. Multiply second equation by 3 and add to first.

Step 1: Multiply second by 3: $6x - 3y = 15$

Step 2: Add to first: $(5x + 3y) + (6x - 3y) = 29 + 15$$11x = 44$$x = 4$

Step 3: Substitute: $2(4) - y = 5 \Rightarrow y = 3$

Solution: $(4, 3)$

Verification: $5(4) + 3(3) = 29$ ✓ and $2(4) - 3 = 5$ ✓

💡 Strategic Tip: Multiplying by 3 creates $-3y$ to cancel $+3y$.

Choice A is incorrect because$2(7) - (-2) = 16 \ eq 5$.

Choice C is incorrect because$5(5) + 3(\frac{4}{3}) = 29$ ✓, but $2(5) - \frac{4}{3} \ eq 5$.

Choice D is incorrect because$5(3) + 3(\frac{14}{3}) = 29$ ✓, but $2(3) - \frac{14}{3} \ eq 5$.
