12y^{-2}-23y^{-1}=-5

12 y^{- 2} - 23 y^{- 1} = - 5

y = \frac{3}{5}, y = 4

Decimal Notation

y = 0.6, y = 4

Solution steps

12 y^{- 2} - 23 y^{- 1} = - 5

Refine

\frac{12}{y ^{2}} - \frac{23}{y} = - 5

Multiply by LCM

12 - 23 y = - 5 y^{2}

Solve

12 - 23 y = - 5 y^{2} : y = \frac{3}{5}, y = 4

y = \frac{3}{5}, y = 4

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = \frac{3}{5}, y = 4

\frac{x}{x ^{2} + 1} = \frac{1}{x}

\frac{4}{5 x + 1} = \frac{9}{10 x + 1}

\frac{8}{x - 2} = \frac{3}{2 x + 1}

\frac{4}{c - 2} = \frac{c - 4}{2}

\frac{9}{3 x - 2} = 1
