9/(-3x)=(12)/(x+10)

\frac{9}{- 3 x} = \frac{12}{x + 10}

x = - 2

Solution steps

\frac{9}{- 3 x} = \frac{12}{x + 10}

Cross multiply

- 3 x - 30 = x \cdot 12

Move

30

to the right side

- 3 x = x \cdot 12 + 30

Move

x 12

to the left side

- 15 x = 30

Divide both sides by

- 15

x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0, x = - 10

Combine undefined points with solutions:

x = - 2

\frac{6}{x + 7} = \frac{8}{x}

\frac{1}{x + 2} + \frac{4}{x ^{2} - 4} = 1

4 = \frac{x ^{2}}{x - 1}

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

a, \frac{1}{a} + \frac{1}{b} = c
