Choice B is the correct answer. Since $x = 2y + 5$ is already isolated, substitute.

Step 1: Substitute into first: $2(2y + 5) - 3y = 11$$4y + 10 - 3y = 11$$y = 1$

Step 2: Find x: $x = 2(1) + 5 = 7$

Solution: $(7, 1)$

Verification: $2(7) - 3(1) = 14 - 3 = 11$ ✓

💡 Strategic Tip: When x is isolated, substitute directly.

Choice A is incorrect because$2(9) - 3(2) = 12 \ eq 11$.

Choice C is incorrect because$2(11) - 3(3) = 13 \ eq 11$.

Choice D is incorrect because$2(5) - 3(0) = 10 \ eq 11$.
