    This is for you. I decided to post a few precalculus problems just for fun.

    Here it is:

    ax + b = bx - a

    ax - bx = -a -b

    x(a - b) = -a - b

    x = -a - b/(a - b)

    if you have it this way, x = -a - b/(a - b) means only - b/(a - b)

    this should be: x = (-a - b)/(a - b) or x = -(a + b)/(a - b)
