3 x + 9 = \frac{5}{x}

x = \frac{- 9 + 141}{6}, x = \frac{- 9 - 141}{6}

Decimal Notation

x = 0.47905 \dots, x = - 3.47905 \dots

Solution steps

3 x + 9 = \frac{5}{x}

Multiply both sides by

x

3 x^{2} + 9 x = 5

Solve

3 x^{2} + 9 x = 5 : x = \frac{- 9 + 141}{6}, x = \frac{- 9 - 141}{6}

x = \frac{- 9 + 141}{6}, x = \frac{- 9 - 141}{6}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{- 9 + 141}{6}, x = \frac{- 9 - 141}{6}

T, v = \frac{2 π r}{T}

\frac{2}{3} = \frac{3}{x}

\frac{1}{y - 3} = \frac{- 1}{3 - y}

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

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