2/(x+8)= 4/x

\frac{2}{x + 8} = \frac{4}{x}

x = - 16

Solution steps

\frac{2}{x + 8} = \frac{4}{x}

Cross multiply

2 x = 4 x + 32

Move

4 x

to the left side

- 2 x = 32

Divide both sides by

- 2

x = - 16

Verify Solutions

Find undefined (singularity) points:

x = - 8, x = 0

Combine undefined points with solutions:

x = - 16

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

(\frac{100}{x} - 1) (x + 5) = 100

y, \frac{x - 2}{y} = z

x + \frac{2 x + 5}{x + 6} = 2

6.46 = \frac{0.5}{x}
