2=(x+4)/(x-8)

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

x = 20

Solution steps

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

Multiply both sides by

x - 8

2 (x - 8) = x + 4

Expand

2 (x - 8) : 2 x - 16

2 x - 16 = x + 4

Move

16

to the right side

2 x = x + 20

Move

x

to the left side

x = 20

Verify Solutions

Find undefined (singularity) points:

x = 8

Combine undefined points with solutions:

x = 20

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

\frac{4}{0.7071 x} = 10

\frac{x}{x + 4} + \frac{7}{x - 2} = 1

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