solvefor r,r= c/(1-r)

solve for

r, r = \frac{c}{1 - r}

r = - \frac{- 1 + 1 - 4 c}{2}, r = - \frac{- 1 - 1 - 4 c}{2}

Solution steps

r = \frac{c}{1 - r}

Multiply both sides by

1 - r

r (1 - r) = c

Solve

r (1 - r) = c : r = - \frac{- 1 + 1 - 4 c}{2}, r = - \frac{- 1 - 1 - 4 c}{2}

r = - \frac{- 1 + 1 - 4 c}{2}, r = - \frac{- 1 - 1 - 4 c}{2}

\frac{2 x ^{4} + 6}{x ^{4}} = 0

\frac{2 x}{5 - x} = \frac{15 - 2 x}{x}

\frac{x}{x - 4} - \frac{2 x}{x + 4} = 1

\frac{1}{4} + \frac{3}{x + 7} = 1

\frac{x}{x + 1} = 1
