(18)/x =x-3

\frac{18}{x} = x - 3

x = 6, x = - 3

Solution steps

\frac{18}{x} = x - 3

Multiply both sides by

x

18 = x^{2} - 3 x

Solve

18 = x^{2} - 3 x : x = 6, x = - 3

x = 6, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6, x = - 3

26 - \frac{1}{x ^{2}} = 0

\frac{7 x - 3}{5 x + 12} = \frac{4 x - 1}{3 x + 4}

\frac{- 9}{\frac{1}{8}} = \frac{36}{x}

\frac{8}{x - 1} = \frac{4}{3}

108 = \frac{567}{x} \times 100
