    For number 1: Notice on this problem that the coefficient in your original equation is 3, but then it becomes 3/5. That should give you a hint that you should divide both sides of the equation by 5, which leads you to (B).

    If you have a graphing calculator, you can figure out most of these problems by graphing the various equations.
