    What do you need help solving. Treat is as if it was a regular equation. Pretend there is a = sign there.

    Can you solve then? Remember anytime you divide by a negative number, you switch the sign (in the end)

    The question says - Solve. -np - 90 < 30 for n.

    So, pretend you have: -np - 90 = 30 can you solve for n now?

    It wouldn't be any different if there was a number on there. Same proceduce.

    So I would have -n - 90 < 30/p ?

    No. First, add 90 to both sides, as i told you to do so earlier. That way, you isolate the -np by itself.

    Then you have: \(\sf \color{red}{-np < 30 + 90}\)

    So now I have -np < 120

    Next divide by \(\sf \sf \color{red}{-p}\) remeber i said when you divide by a negative number, you re actually flipping the sign of the inequality.

    And you've solved for it.

    So -n>120/p is the answer?

    Can you also help me with 5m - 3h = 45

    No. you cannot have a negative answer, it must be positive! It wouldn't make sense to say a negative number is greater than a positive, assuming p > 0

    5m-3h = 45 what are you solving for?
