x/(x+3)= 3/2

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

x = - 9

Solution steps

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

Cross multiply

x \cdot 2 = 3 x + 9

Move

3 x

to the left side

- x = 9

Divide both sides by

- 1

x = - 9

Verify Solutions

Find undefined (singularity) points:

x = - 3

Combine undefined points with solutions:

x = - 9

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

x^{- 2} + x^{- 1} = 6

- \frac{3}{( x - 5 ) ^{2}} = 0

\frac{4 x}{x - 2} + \frac{6}{x + 2} = 3

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