20x-9=(20)/x

20 x - 9 = \frac{20}{x}

x = \frac{5}{4}, x = - \frac{4}{5}

Solution steps

20 x - 9 = \frac{20}{x}

Multiply both sides by

x

20 x^{2} - 9 x = 20

Solve

20 x^{2} - 9 x = 20 : x = \frac{5}{4}, x = - \frac{4}{5}

x = \frac{5}{4}, x = - \frac{4}{5}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{5}{4}, x = - \frac{4}{5}

\frac{1}{x} = 0.4

\frac{180 ( n - 2 )}{n} = 12

\frac{1}{x + 1} + \frac{1}{x + 2} = 0

1 = \frac{12 x ^{2}}{x ^{4} + 36}

- \frac{2}{9} = \frac{5}{x}
