    You posted this twice. I was hoping you'd do the second one yourself, after seeing how I did the first one.

    When you combine similar terms on the left side of
    3+3x-(x-2)=3x+4
    you get
    2x + 5 = 3x + 4
    For the next step, subtract 2x from both sides of the equation.
    5 = x + 4
    From there, you should be able to solve for x in one more step.
