\frac{4}{5 x} - 3 = 0

x = \frac{4}{15}

Decimal Notation

x = 0.26666 \dots

Solution steps

\frac{4}{5 x} - 3 = 0

Multiply both sides by

5 x

4 - 15 x = 0

Move

4

to the right side

- 15 x = - 4

Divide both sides by

- 15

x = \frac{4}{15}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{4}{15}

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

\frac{- 5}{3 x} = - 26

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

x, \frac{1}{a x} + 7 = 25
