q/t=q/p+1 Express p in terms of q & t
(I'm using / as a fraction thing)
Solve 2 over x-1 minus 3 over x+1 equals 1 over 15
(12-2x)(10-2x)=80
Find the value of x
Thanks for any help, I'll probably need more

(1) $\displaystyle \frac{q}{t}=\frac{q}{p}+1$
$\displaystyle \frac{q}{t}-1=\frac{q}{p}$
finally i get $\displaystyle p=\frac{qt}{q-t}$
(2)$\displaystyle \frac{2}{x-1}-\frac{3}{x+1}=\frac{1}{15}$
Try equating the denominator first
$\displaystyle \frac{2(x+1)-3(x-1)}{(x-1)(x+1)}=\frac{1}{15}$
After that cross multiply and solve for x ..
(3) $\displaystyle (12-2x)(10-2x)=80$
some expansion is required here
$\displaystyle 120-24x-20x+4x^2-80=0$
Can u continue from here ?
