\frac{12}{x} = \frac{30}{6}

x = \frac{12}{5}

Solution steps

\frac{12}{x} = \frac{30}{6}

x \cdot 30 = 72

Divide both sides by

30

x = \frac{12}{5}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{12}{5}

\frac{8}{x + 3} + \frac{10}{x} = 3

\frac{5}{4 x} + \frac{1}{x} = 3

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

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

9 x^{- 4} - 10 x^{- 2} + 1 = 0
