x = 2, x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 2

10 x = 1 + \frac{3}{x}

\frac{8}{x + 9} = \frac{5}{x - 3}

\frac{x - 7}{5 x} + 1 = \frac{x + 3}{x}

\frac{3}{( x - 2 )} = \frac{4 - 1}{3}

\frac{3}{2 y} = \frac{16}{y + 2}
