An equation and the steps to solve it are shown below:

7x - one over two (8x + 4) = 6

Step 1: 7x - 4x - 2 = 6

Step 2: 3x - 2 = 6

Step 3: 3x - 2 + 2 = 6

Step 4: 3x = 6

Step 5: x = 2

Which step was the error made and why?

Step 1, because incorrect signs have been used

Step 2, because the terms have been added incorrectly

Step 3, because a number has been added only to one side of the equation

No error was made
