    You need to isolate the variable. So, subtract 7 from both sides.

    The only thing you really have to remember is that when multiplying or dividing by a negative number, the sign flips.

    Yes, that is correct! You don't have to do any graphing or such right?

    If you divide by a negative, you flip the sign.

    You had the correct answer, the sign just needed to be flipped.

    it simplifies to -7/8 (you accidentally cancelled the negative) final answer would be \[r \ge \frac{ -7 }{ 8 }\]
