x-4= 5/x

x - 4 = \frac{5}{x}

x = 5, x = - 1

Solution steps

x - 4 = \frac{5}{x}

Multiply both sides by

x

x^{2} - 4 x = 5

Solve

x^{2} - 4 x = 5 : x = 5, x = - 1

x = 5, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 5, x = - 1

\frac{( n + 1 ) !}{( n - 1 ) !} = 56

\frac{x}{x - 2} = 0

\frac{3}{5} = \frac{3}{x}

\frac{x}{x + 6} = \frac{4}{x - 4}

\frac{t - 1}{1 - t} = \frac{3}{2}
