Choice D is the correct answer. Use elimination by multiplying the second equation by 3.

Step 1: Multiply second equation by 3: $12x + 3y = 57$

Step 2: Add to first equation: $(2x - 3y) + (12x + 3y) = 1 + 57$$14x = 58$$x = \frac{58}{14} = \frac{29}{7}$

Non-integer. - First: $2(4) - 3(3) = 8 - 9 = -1 \ eq 1$

• Second: $4(4) + 3 = 19$ ✓

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

**Choice A is incorrect.

Choice B is incorrect because$2(5) - 3(3) = 1$ ✓, but $4(5) + 3 = 23 \ eq 19$.

**Choice C is incorrect.
