x^{-1}=1

Solution

x^{- 1} = 1

x = 1

Solution steps

x^{- 1} = 1

Refine

\frac{1}{x} = 1

Multiply both sides by

x

1 = x

Switch sides

x = 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1

x^{- 1} = 3

\frac{2.5}{6} = \frac{4}{m}

\frac{x}{x ^{2}} = 25

\frac{25}{x} = 5

\frac{5}{x - 2} = \frac{4}{x - 1}
