Set 5: Systems of Equations

Choice C is correct. Choice C is the correct answer. Multiply second by 2 and add to first. Step 1: Multiply second by 2: $8x - 2 y = 26$ Step 2: Add to first: (3 x + 2 y) + (8 x - 2 y) = 17 + 26$11x = 43$x = \frac{43}{11} Non-integer. - First: $3(3) + 2(4) = 9 + 8 = 17$ ✓ - Second: $4(3) - 4 = 12 - 4 = 8 \neq 13$ Strategic Tip: Multiplying by 2 creates $-2 y$ to cancel $+2 y$. Other choices fail verification.
