\frac{x}{5} = \frac{7}{x}

x = 35, x = - 35

Solution steps

\frac{x}{5} = \frac{7}{x}

Cross multiply

x^{2} = 35

Solve

x^{2} = 35 : 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

r, θ = \frac{s}{r}

(y - 2)^{2} = \frac{25}{81 y}

\frac{- 2}{x - 1} = \frac{x - 8}{x + 1}

\frac{1}{y - 1} + 1 = \frac{2}{y - 1}

\frac{3}{x} + 3 = - 2
