-1-4/x =-5x

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

x = - \frac{4}{5}, x = 1

Decimal Notation

x = - 0.8, x = 1

Solution steps

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

Multiply both sides by

x

- x - 4 = - 5 x^{2}

Solve

- x - 4 = - 5 x^{2} : x = - \frac{4}{5}, x = 1

x = - \frac{4}{5}, x = 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - \frac{4}{5}, x = 1

\frac{2 x}{x + 2} = \frac{3 x}{x + 5} - 1

y, \frac{2}{x} - \frac{1}{y} = 4

- \frac{2}{x ^{2}} + \frac{1}{x} + 3 = 0

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

\frac{1}{2 x} = \frac{( r - x )}{7}
