-9/(x+9)-1=(8x)/(x+9)

- \frac{9}{x + 9} - 1 = \frac{8 x}{x + 9}

x = - 2

Solution steps

- \frac{9}{x + 9} - 1 = \frac{8 x}{x + 9}

Multiply both sides by

x + 9

- 9 - (x + 9) = 8 x

Expand

- 9 - (x + 9) : - x - 18

- x - 18 = 8 x

Move

18

to the right side

- x = 8 x + 18

Move

8 x

to the left side

- 9 x = 18

Divide both sides by

- 9

x = - 2

Verify Solutions

Find undefined (singularity) points:

x = - 9

Combine undefined points with solutions:

x = - 2

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

\frac{3}{x ^{2}} - \frac{50}{x} = 17

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

\frac{5 x - 3}{x} + \frac{x - 1}{5} = 2

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