x = - 4

Solution steps

3 + \frac{10}{x} = \frac{1}{2}

Multiply by LCM

6 x + 20 = x

Move

20

to the right side

6 x = x - 20

Move

x

to the left side

5 x = - 20

Divide both sides by

5

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 4

x - 2 - \frac{( x - 2 ) ( x - 1 )}{x - 1} = 0

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

f, f^{- 1} (x) = x^{3} + 8

\frac{( n + 2 ) !}{n !} = 12

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