x-1= 2/x

x - 1 = \frac{2}{x}

x = 2, x = - 1

Solution steps

x - 1 = \frac{2}{x}

Multiply both sides by

x

x^{2} - x = 2

Solve

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

x = 2, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 1

\frac{21}{p} = 15

\frac{8}{x ^{2}} - \frac{8}{x} = 6

\frac{6}{b} = - \frac{3}{2}

- \frac{245}{54} = - \frac{7}{x - 4}

\frac{5}{a - 7} = \frac{40}{1}
