-2=(10-20)/x

- 2 = \frac{10 - 20}{x}

x = 5

Solution steps

- 2 = \frac{10 - 20}{x}

Simplify

\frac{10 - 20}{x} : - \frac{10}{x}

- 2 = - \frac{10}{x}

Multiply both sides by

x

- 2 x = - 10

Divide both sides by

- 2

x = 5

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 5

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

\frac{1}{x} + \frac{1}{5 x} = 6

\frac{x}{3} + \frac{x - 1}{x} = \frac{7}{6}

\frac{4}{x} + \frac{2 ( x + 1 )}{3 ( x - 2 )} = 4

2 - \frac{3 x - 2}{x + 1} = \frac{x - 4}{2 x - 3}
