\[(1/r) + (r/(2-r))=-7/4\]

\(\dfrac{1}{r}+\dfrac{r}{2-r}=-\dfrac{7}{4}\) It looks like you need a common denominator.

I multiplied the entire equation through by each denominator to eliminate the fractions.

Do the denominator calculus of the left equation. Will be: r(r - 2). After, do the normal account. Will be: \[\dfrac{-r^2-r+2}{(r-2)r}=-\dfrac{7}{4}\] Now continue the calculus doing the cross multiplying.
