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).

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
