    The error comes between steps 1 and 2.

    Step-by-step explanation:

    When we combine the like terms of 4x and - 5x, then we get a - x. The problem above shows a positive x, which is incorrect.

    In Step 2 an error was made, for the person solving this problem added the like terms incorrectly. If you are to subtract 5x (or add - 5x) from (to) 4x, you would get the answer of - x or - 1x. Therefore, the equation would be - x - 2 = 4.
