Is (3,4)(3, 4) a solution to the system? {y=2x2y=x+1\begin{cases} y = 2x - 2 \\ y = x + 1 \end{cases}

A

No

B

Yes

C

Only for the second equation

D

Cannot be determined

Correct Answer: B

Choice B is the correct answer. Let's check Choice A is incorrect because the point does satisfy both equations.

Choice C is incorrect because the point satisfies both equations, not just the second one.

Choice D is incorrect because we can always determine if a point is a solution by direct substitution.
