x+(12)/x =7

x + \frac{12}{x} = 7

x = 4, x = 3

Solution steps

x + \frac{12}{x} = 7

Multiply both sides by

x

x^{2} + 12 = 7 x

Solve

x^{2} + 12 = 7 x : x = 4, x = 3

x = 4, x = 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = 3

\frac{n - 6}{n - 7} = \frac{9}{2}

\frac{4}{x} = \frac{29}{8 x} + 3

\frac{7}{x + 4} = \frac{9}{5 x - 6}

\frac{3}{x - 6} = \frac{7}{x + 2}

\frac{3 x}{2 x - 1} = \frac{2 x + 1}{x}
