    Hm... now it seems you missed the plus sign...

    You need to solve for x?

    Use the distributive law first.





    Simplify now and send all the terms in x on one side and all the other terms on another side of the equal sign.

    Can you get it now? Post what you get! :)

    hmm yeah I did misplaced a plus sign
    I then subtract 2 from oppisites sides of the equation which leaves me with
    3x + 1 = -2x - 4
    -1 -1
    3x = -2x -5
    -2x -2x
    x = -5

    Not quite.



    Add 2x, not subtract.

    Because -2x -2x = -4x.

    So, in your work, you are doing:

    3x - 2x = -2x -5 - 2x

    x = -4x -5
