8 x - \frac{2}{5 x} + 7 = 3

x = \frac{- 5 + 3 5}{20}, x = - \frac{5 + 3}{4 5}

Solution steps

8 x - \frac{2}{5 x} + 7 = 3

Move

7

to the right side

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

Multiply both sides by

5 x

40 x^{2} - 2 = - 20 x

Solve

40 x^{2} - 2 = - 20 x : x = \frac{- 5 + 3 5}{20}, x = - \frac{5 + 3}{4 5}

x = \frac{- 5 + 3 5}{20}, x = - \frac{5 + 3}{4 5}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{- 5 + 3 5}{20}, x = - \frac{5 + 3}{4 5}

\frac{x + 2}{14} = \frac{14}{x + 2}

\frac{1}{2 x + 4} = 7 \frac{1}{2}

\frac{- 7}{y - 2} = - 4

\frac{250}{100} = \frac{0.5}{x}

\frac{3}{- 4 + 2 y} = \frac{5}{6}
