    hmm but I don't see how we can add multiply or subtract them since they all have different variables

    Not quite... how would you isolate a on one side? You would have to divide EACH side by 6.

    You're missing a sign, what is a negative divided by a positive?

    well in this case -24 is bigger than 6 so its -4
