Question

y = - 1 5 x y = 1 7 x The solution to the given system of equations is x , y . What is the value of x ?

Accepted Answer

Choice B is correct. It's given by the first equation in the system that y = - 1 5 x . Substituting - 1 5 x for y in the second equation in the system, y = 1 7 x , yields - 1 5 x = 1 7 x . Adding - 1 5 x to both sides of this equation yields 0 = 1 7 x + 1 5 x , which is equivalent to 0 = 5 35 x + 7 35 x , or 0 = 12 35 x . Multiplying both sides of this equation by 35 12 yields 0 = x . Therefore, the value of x is 0 . Choice A 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.
