to the right side

x = \frac{17}{2}

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = \frac{17}{2}

\frac{3}{x} - \frac{1}{3} = - 6

\frac{- 2}{x - 2} + \frac{1}{x + 4} = 1

\frac{x}{8} = \frac{8}{x}

\frac{f}{5 n ^{3}} + h = g

\frac{5}{x} = \frac{5}{6 x} - 3
