5/(9+2x)= 3/x

\frac{5}{9 + 2 x} = \frac{3}{x}

x = - 27

Solution steps

\frac{5}{9 + 2 x} = \frac{3}{x}

Cross multiply

5 x = 27 + 6 x

Move

6 x

to the left side

- x = 27

Divide both sides by

- 1

x = - 27

Verify Solutions

Find undefined (singularity) points:

x = - \frac{9}{2}, x = 0

Combine undefined points with solutions:

x = - 27

\frac{2}{x - 1} = \frac{4}{3 x + 2}

\frac{4}{t} = \frac{5}{3}

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

0.25118 = \frac{R}{10000 + R}

\frac{- 1}{2 x + 2 + y} = 0
