2/(x+4)= 3/x

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

x = - 12

Solution steps

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

Cross multiply

2 x = 3 x + 12

Move

3 x

to the left side

- x = 12

Divide both sides by

- 1

x = - 12

Verify Solutions

Find undefined (singularity) points:

x = - 4, x = 0

Combine undefined points with solutions:

x = - 12

- 2 = \frac{1}{x}

\frac{9 x}{36 x} = x^{2}

\frac{2 x - 7}{x} = \frac{x - 4}{3}

\frac{60}{f} = 12

\frac{x - 4}{5} = \frac{- 2}{x + 3}
