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. - May 16th 2006, 03:41 PMineedhelp2pass
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 - May 16th 2006, 03:58 PMJameson
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.
