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

x = 35, x = - 35

Decimal Notation

x = 6.70820 \dots, x = - 6.70820 \dots

Solution steps

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

Cross multiply

45 = x^{2}

Solve

45 = x^{2} : x = 35, x = - 35

x = 35, x = - 35

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 35, x = - 35

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

0.4286 = 1 - 26 + \frac{273}{x}

\frac{6}{24} = \frac{21}{x}

\frac{2 - x}{x ^{2} + 5} = 0

\frac{2}{x} = \frac{2}{5}
