No, if the door is 42 inches wide(across), and the table is 96 inches in diameter(across), then it will not fit vertically or horizontally through the door because its diameter is greater than both the width and the height of the door.
Option B.
Given that the equation 7x − 8y = 6 is multiplied by 1 and it is added to the first equation the new equation is
7x - 8y + x + 3y = 5 + 6; equivalent to
8x -5y =11; and the system is that equation with the second original one.
7x- 8y = 6
