3 y = 4 x + 17 - 3 y = 9 x - 23 The solution to the given

Question

3 y = 4 x + 17 - 3 y = 9 x - 23 The solution to the given system of equations is x , y . What is the value of 39 x ?

Accepted Answer

Choice D is correct. Adding the second equation to the first equation in the given system of equations yields 3 y - 3 y = 4 x + 9 x + 17 - 23 , or 0 = 13 x - 6 . Adding 6 to each side of this equation yields 6 = 13 x . Multiplying each side of this equation by 3 yields 18 = 39 x . Therefore, the value of 39 x is 18 . Choice A is incorrect. This is the value of - 39 x , not 39 x . Choice B is incorrect. This is the value of - 13 x , not 39 x . Choice C is incorrect. This is the value of 13 x , not 39 x .
