x-4/x =3

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

x = 4, x = - 1

Solution steps

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

Multiply both sides by

x

x^{2} - 4 = 3 x

Solve

x^{2} - 4 = 3 x : x = 4, x = - 1

x = 4, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = - 1

\frac{( x - 0.4 ) ^{2}}{2 + x} = 1.59

\frac{x - 1}{x} = \frac{x + 11}{5}

x, \frac{8.9}{x} + 2 = 8

\frac{10}{x} = 0.3

\frac{x - 3}{2} - \frac{2 x}{x + 2} = 0
