- 4 x + \frac{4}{x} = 0

x = 1, x = - 1

Solution steps

- 4 x + \frac{4}{x} = 0

Multiply both sides by

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = - 1

\frac{2 x + 3}{2} - \frac{3 x}{x - 4} = x

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

\frac{12}{t} + t - 8 = 0

\frac{2 z + 6}{z + 2} = 3 - \frac{1}{z}

\frac{2}{z} = 0.05
