(12)/(x+1)= 9/(x-6)

\frac{12}{x + 1} = \frac{9}{x - 6}

x = 27

Solution steps

\frac{12}{x + 1} = \frac{9}{x - 6}

Cross multiply

12 x - 72 = 9 x + 9

Move

72

to the right side

12 x = 9 x + 81

Move

9 x

to the left side

3 x = 81

Divide both sides by

3

x = 27

Verify Solutions

Find undefined (singularity) points:

x = - 1, x = 6

Combine undefined points with solutions:

x = 27

- \frac{3}{x} + \frac{3}{8 x} = 21

\frac{7}{x} = \frac{11}{3 x} - 8

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

\frac{1}{x + 3} + 2 = \frac{11}{x + 3}

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