solving equations
i have a problem solving equations.they aren't your basic equations.
here's an example.
negative 7 over 8 (-7/8p) + 1 1/4=18

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.
