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

x = 9, x = - 9

Solution steps

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

Cross multiply

81 = x^{2}

Solve

81 = x^{2} : x = 9, x = - 9

x = 9, x = - 9

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 9, x = - 9

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

\frac{7}{2 x ^{2}} + 5 x = - 51

\frac{5 A - 3}{2 A + 1} = \frac{2}{7}

\frac{( 3 )}{( x )} = 6

(\frac{28}{y})^{2} + y^{2} = 65
