hey all

could anyone jst help me set up this equation please

question goes like this

The volume of a liquid V cm3 at time t seconds satisfies

-15DV/dt = 2V - 450

can anyone express that in the form 1/g(y) = f(x) please
i got -15/2v = -450. Is that correct because it dnt seem to work?

thanks

Divide both sides by 2V - 450.

\newline \displaystyle \frac{-15}{2V - 450}\frac{\mbox{d}V}{\mbox{d}t} = 1
