x - 2 - 4 y + 7 = 117 x - 2 + 4 y + 7 = 442

Question

x - 2 - 4 y + 7 = 117 x - 2 + 4 y + 7 = 442 The solution to the given system of equations is x , y . What is the value of 6 x - 2 ?

Accepted Answer

The correct answer is 1,677 . Adding the first equation to the second equation in the given system yields x - 2 + x - 2 + - 4 y + 7 + 4 y + 7 = 117 + 442 , or 2 x - 2 = 559 . Multiplying both sides of this equation by 3 yields 6 x - 2 = 1,677 . Therefore, the value of 6 x - 2 is 1,677 .
