Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{84}{5}

(x - 2) (\frac{800}{x} + 20) = 800

\frac{1}{R} = \frac{R ^{1} + R ^{2}}{R ^{1} R ^{2}}

\frac{8}{3} = \frac{2 x}{3 x - 15}

7 = \frac{x ^{2 + 10}}{x}

\frac{5 - 6 x}{x ^{2} - 9} = 0
