- 19

j = \frac{2}{19}

Verify Solutions

Find undefined (singularity) points:

j = 0

Combine undefined points with solutions:

j = \frac{2}{19}

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

\frac{2}{b + 1} = \frac{5}{2}

\frac{8}{2 x} = 4 - \frac{2}{x}

\frac{3}{x - 2} = \frac{5}{9 x - 2}

\frac{12}{x} + \frac{18}{x + 4} = 9
