\frac{3}{4 x} = \frac{5}{6}

x = \frac{9}{10}

Decimal Notation

x = 0.9

Solution steps

\frac{3}{4 x} = \frac{5}{6}

Divide both sides by

20

x = \frac{9}{10}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{9}{10}

z^{5} + 8 \cdot z^{- 1} = 0

z = \frac{1}{z}

\frac{2}{x + 8} = \frac{4}{x}

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

(\frac{100}{x} - 1) (x + 5) = 100
