x = \frac{- 71 + 6985}{18}, x = \frac{- 71 - 6985}{18}

Decimal Notation

x = 0.69868 \dots, x = - 8.58757 \dots

Solution steps

\frac{6}{x} + \frac{4}{x + 9} = 9

Multiply by LCM

6 (x + 9) + 4 x = 9 x (x + 9)

Solve

6 (x + 9) + 4 x = 9 x (x + 9) : x = \frac{- 71 + 6985}{18}, x = \frac{- 71 - 6985}{18}

x = \frac{- 71 + 6985}{18}, x = \frac{- 71 - 6985}{18}

Verify Solutions

Find undefined (singularity) points:

x = 0, x = - 9

Combine undefined points with solutions:

x = \frac{- 71 + 6985}{18}, x = \frac{- 71 - 6985}{18}

\frac{3 x - \frac{7}{2}}{2 x} = 5

\frac{1}{4 - y} + \frac{1}{y} - 8 = 0

\frac{2 x - 5}{x} = \frac{x - 3}{2}

\frac{2 x ^{2}}{5 x - 6} = 2

y, C = \frac{r}{y}
