    @LaurenAshley1201 You can also use Wolfram Alpha as well, it will solve equations for you in seconds and will show you with steps on how to get your answer.

    @RyanL. Of course, it's just useful. I live in a different time zone from most people on here and sometimes nobody is online when I ask a question!
