x/2-3+4/x =0

\frac{x}{2} - 3 + \frac{4}{x} = 0

x = 4, x = 2

Solution steps

\frac{x}{2} - 3 + \frac{4}{x} = 0

Multiply by LCM

x^{2} - 6 x + 8 = 0

Solve

x^{2} - 6 x + 8 = 0 : x = 4, x = 2

x = 4, x = 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = 2

\frac{3 y + 5}{6 y - 4} = \frac{3}{4}

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

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

\frac{x ^{2} - 4 x}{x - 2} = \frac{14 - 9 x}{x - 2}

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