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

Step 1: Multiply first by 2: $10x - 4y = 26$

Step 2: Add to second: $(10x - 4y) + (3x + 4y) = 26 + 27$$13x = 53$$x = \frac{53}{13}$

Non-integer. - First: $5(5) - 2(3) = 25 - 6 = 19 \ eq 13$

• Second: $3(5) + 4(3) = 15 + 12 = 27$ ✓

💡 Strategic Tip: Multiplying by 2 creates $-4y$ to cancel $+4y$.

**Other choices fail verification.
