2/(x-3)= 8/(x+3)

\frac{2}{x - 3} = \frac{8}{x + 3}

x = 5

Solution steps

\frac{2}{x - 3} = \frac{8}{x + 3}

Cross multiply

2 x + 6 = 8 x - 24

Move

6

to the right side

2 x = 8 x - 30

Move

8 x

to the left side

- 6 x = - 30

Divide both sides by

- 6

x = 5

Verify Solutions

Find undefined (singularity) points:

x = 3, x = - 3

Combine undefined points with solutions:

x = 5

\frac{20}{x} = 3

- \frac{3}{x} = - 6

(0.1) (\frac{2}{n} + 1) = 3

x^{2} - 9 = \frac{x + 3}{( x - 2 )}

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