Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 20

- \frac{4 x + 8}{x ^{2} - 9} = \frac{5 x + 1}{x + 3}

1 + \frac{1}{x} = \frac{6}{x ^{2}}

\frac{6}{z} = \frac{3}{5}

\frac{3}{x - 3} - \frac{6}{x ^{2}} = 0

\frac{4 x}{3 x - 12} + 3 = 10
