Mmk. So $\displaystyle -\frac{7}{8p}+\frac{5}{4}=18$ Let's get rid of the denominators by multiplying everything by 8p. $\displaystyle -7+10p=144p$ 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 $\displaystyle -\frac{7}{8}p+\frac{5}{4}=18$ Multiply again by 8 and yield $\displaystyle -7p+10=144$ Now you can solve this.
