x-(12)/x =-4

x - \frac{12}{x} = - 4

x = 2, x = - 6

Solution steps

x - \frac{12}{x} = - 4

Multiply both sides by

x

x^{2} - 12 = - 4 x

Solve

x^{2} - 12 = - 4 x : x = 2, x = - 6

x = 2, x = - 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 6

\frac{x}{x + 1} + \frac{x + 1}{x} = \frac{13}{6}

\frac{5 x}{x - 4} = \frac{3 x}{2 x + 7}

\frac{3}{x} + \frac{2}{x - 1} = 6

\frac{32 x}{( 25 - x ^{2} ) ^{2}} = 0

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