Find the error in the calculations below, if there is one: Line (1): 8x – 4 = 2(4x + 1) – 6 Line (2): 8x – 4 = 8x + 1 - 6 Line (3): 8x - 4 = 8x – 5 Line (4): -4 = - 5 Line (5): Based on the calculations above, there are no solutions. The error occurred from line (1) to line (2). The error occurred from line (2) to line (3). The error occurred from line (3) to line (4). The error is in line (5).​
