9/(x+2)-1=0

\frac{9}{x + 2} - 1 = 0

x = 7

Solution steps

\frac{9}{x + 2} - 1 = 0

Multiply both sides by

x + 2

9 - (x + 2) = 0

Move

9

to the right side

- (x + 2) = - 9

Divide both sides by

- 1

x + 2 = 9

Move

2

to the right side

x = 7

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = 7

(1 - 8000 r)^{- 1} = 1 + r (10000)

0.1875 = \frac{1000}{x + 1000}

\frac{x ^{2} + x}{1 - x ^{2}} = 0

\frac{3 x}{x - 4} - \frac{2}{x} = 3

x + \frac{1}{x} = 3 \frac{11}{14}
