(x+1)/(1-2x)= 5/(-7)

\frac{x + 1}{1 - 2 x} = \frac{5}{- 7}

x = 4

Solution steps

\frac{x + 1}{1 - 2 x} = \frac{5}{- 7}

Cross multiply

- 7 x - 7 = 5 - 10 x

Move

7

to the right side

- 7 x = - 10 x + 12

Move

10 x

to the left side

3 x = 12

Divide both sides by

3

x = 4

Find undefined (singularity) points:

x = \frac{1}{2}

Combine undefined points with solutions:

x = 4

- \frac{9}{x + 9} - 1 = \frac{5 x}{x + 9}

\frac{1}{x - 7} - 1 = - \frac{9 x}{x - 7}

\frac{x - 6}{x - 13} = - 6

\frac{40}{x - 2} - \frac{40}{x} - 1 = 0

\frac{3}{x + 1} + \frac{2}{7} = 2
