5/(x-3)= 7/(x-9)

\frac{5}{x - 3} = \frac{7}{x - 9}

x = - 12

Solution steps

\frac{5}{x - 3} = \frac{7}{x - 9}

Cross multiply

5 x - 45 = 7 x - 21

Move

45

to the right side

5 x = 7 x + 24

Move

7 x

to the left side

- 2 x = 24

Divide both sides by

- 2

x = - 12

Verify Solutions

Find undefined (singularity) points:

x = 3, x = 9

Combine undefined points with solutions:

x = - 12

\frac{9}{x - 2} = 5 - \frac{6}{x - 2}

B, r^{3} = \frac{f}{B} + h

\frac{a x - b}{c + x} = d

\frac{a}{a + x} + \frac{a}{a - x} = b

\frac{3}{x + 4} - 7 = \frac{- 4}{x + 4}
