x-(18)/x =3

x - \frac{18}{x} = 3

x = 6, x = - 3

Solution steps

x - \frac{18}{x} = 3

Multiply both sides by

x

x^{2} - 18 = 3 x

Solve

x^{2} - 18 = 3 x : x = 6, x = - 3

x = 6, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6, x = - 3

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

\frac{2 π}{x} = π

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

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

\frac{2 π}{x} = 4
