    This is what I've done so far. => (2x+1) > 0 => x > -1/2 Not sure if that's right.

    It should actually be -1/2 < x < 0. I can't figure out how to get the 0. It is correct logically.

    Thanks! Do you have a solution that can be written using mathematical symbols (i.e not a graph)?

    I think I figured it out. I used a sign table.
