(x-10)/(x-9)= 10/11

\frac{x - 10}{x - 9} = \frac{10}{11}

x = 20

Solution steps

\frac{x - 10}{x - 9} = \frac{10}{11}

Cross multiply

11 x - 110 = 10 x - 90

Move

110

to the right side

11 x = 10 x + 20

Move

10 x

to the left side

x = 20

Verify Solutions

Find undefined (singularity) points:

x = 9

Combine undefined points with solutions:

x = 20

x^{- 2} + 10 x^{- 1} + 9 = 0

\frac{2}{x} + \frac{4}{3} - \frac{5}{2 x} = 1

0 = \frac{- 2 x - 2}{2 x - 12}

x, \frac{1}{a} = \frac{2}{x} + \frac{y}{2}

0.5 = \frac{20 x}{x ^{2} + 4}
