3=x^{-1}

3 = x^{- 1}

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

3 = x^{- 1}

Refine

3 = \frac{1}{x}

Multiply both sides by

x

3 x = 1

Divide both sides by

3

x = \frac{1}{3}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{3}

\frac{2 x ^{2} + 8 x}{3 x + 12} = - 4

2 - (y - 7)^{- 1} = 6 (y - 7)^{- 2}

18.06 = \frac{x ^{2}}{x + 1}

\frac{- 2}{c} = 2

f^{- 1} (- 2) = - 2 + 3
