2=(x+11)/(x-9)

2 = \frac{x + 11}{x - 9}

x = 29

Solution steps

2 = \frac{x + 11}{x - 9}

Multiply both sides by

x - 9

2 (x - 9) = x + 11

Expand

2 (x - 9) : 2 x - 18

2 x - 18 = x + 11

Move

18

to the right side

2 x = x + 29

Move

x

to the left side

x = 29

Verify Solutions

Find undefined (singularity) points:

x = 9

Combine undefined points with solutions:

x = 29

i = \frac{p n}{p n + 1}

9.70802 = \frac{11.9}{t}

- 1000 \cdot (\frac{0.8}{x}) = - 9

x, u = \frac{k}{x}

1 + \frac{x}{x - 5} = \frac{1}{x - 5}
