Question

x + 3 = - 2 y + 5 x - 3 = 2 y + 7 The solution to the given system of equations is x , y . What is the value of 2 x ?

Accepted Answer

Choice C is correct. Adding the second equation in the given system to the first equation in the given system yields x + 3 + x - 3 = - 2 y + 5 + 2 y + 7 . Adding like terms in this equation yields 2 x = 12 . Thus, the value of 2 x is 12 . Choice A is incorrect. This is the value of y , not 2 x . Choice B is incorrect. This is the value of x , not 2 x . Choice D is incorrect and may result from conceptual or calculation errors.
