    Mmk. So -\frac{7}{8p}+\frac{5}{4}=18

    Let's get rid of the denominators by multiplying everything by 8p.

    -7+10p=144p

    And I think you can solve from here.

    i think i might have typed it wrong
    on the 7/8 part the p is after it
    like
    7
    --p
    8
    7/8 times p

    Oh ok.

    Well then you have -\frac{7}{8}p+\frac{5}{4}=18

    Multiply again by 8 and yield -7p+10=144

    Now you can solve this.
