Choice A is the correct answer. Elimination method.

1. Add equations: $(x + y) + (x - y) = 5 + 1 \rightarrow 2x = 6 \rightarrow x = 3$.
2. Substitute: $3 + y = 5 \rightarrow y = 2$.
3. Point: $(3, 2)$.

💡 Strategic Tip: Adding equations is often faster than substitution.

Choice B is incorrect because$2-3 eq 1$. Choice C is incorrect because$4-1 eq 1$ (wait, $4-1=3 eq 1$). Choice D is incorrect because$3+(-2) eq 5$.
