\frac{20 x ^{3}}{x} = 20

x = 1, x = - 1

Solution steps

\frac{20 x ^{3}}{x} = 20

Simplify

\frac{20 x ^{3}}{x} : 20 x^{2}

20 x^{2} = 20

Solve

20 x^{2} = 20 : x = 1, x = - 1

x = 1, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = - 1

x + 5 = \frac{1}{x}

\frac{2}{x - 2} + 5 = \frac{17}{x - 2}

37.5 = \frac{150}{( 334.76811 - x )}

9 = \frac{78}{x}

\frac{32}{x} = \frac{x}{2}
