    I'm pretty sure this is a simple question, though. I'm fairly certain the answer's D, but I could be tricking myself :V

    Another way of setting this problem up is like \[-1 * 6y\] and \[-1 * -4z\]. Are you able to solve from there?

    All you really need to do is distribute the negative sign to the rest of the problem to open the parenthesis

    Signs rules: (+)(+) = + (-)(+) = - (+)(-) = - (-)(-) = +

    Is it B then since it's distributive?
