y = 2x + 3 x = 1 What is the solution (x, y) to the given system of equations?

The correct answer is B. Choice B is correct. Since it's given that x = 1 , substituting 1 for x in the first equation yields y = 2 × 1 + 3 . Simplifying the right-hand side of this equation yields y = 2 + 3 , or y = 5 . Therefore, the ordered pair (1, 5) is a solution to the given system of equations.

Choice A

Choice A is incorrect and may result from a calculation error when substituting $1$ for $x$ in the first equation.

Choice C

Choice C is incorrect. Because it's given that $x = 1$ , $x$ cannot equal $2$ as stated in this ordered pair.

Choice D

Choice D is incorrect. Because it's given that $x = 1$ , $x$ cannot equal $2$ as stated in this ordered pair.
