x + 7 = 10 x + 7 2 = y Which ordered pair x , y is a solution

Question

x + 7 = 10 x + 7 2 = y Which ordered pair x , y is a solution to the given system of equations?

Accepted Answer

Choice A is correct. The solution to a system of equations is the ordered pair x , y that satisfies all equations in the system. It's given by the first equation in the system that x + 7 = 10 . Substituting 10 for x + 7 into the second equation yields 10 2 = y , or y = 100 . The x -coordinate of the solution to the system of equations can be found by subtracting 7 from both sides of the equation x + 7 = 10 , which yields x = 3 . Therefore, the ordered pair 3 , 100 is a solution to the given system of equations. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
