3/9 = 2/(v+2)

\frac{3}{9} = \frac{2}{v + 2}

v = 4

Solution steps

\frac{3}{9} = \frac{2}{v + 2}

Cross multiply

3 (v + 2) = 18

Divide both sides by

3

v + 2 = 6

Move

2

to the right side

v = 4

Verify Solutions

Find undefined (singularity) points:

v = - 2

Combine undefined points with solutions:

v = 4

\frac{2 π}{x} = 5

\frac{10}{4} = \frac{x - 8}{x + 9}

\frac{7 x + 12}{4 x + 3} = \frac{2}{5}

\frac{1}{2 x + 8} = 88

\frac{9 x}{x + 1} = 6 - \frac{9}{x + 1}
