2v-8+12v+4=-2\left(v+9\right)
Use the distributive property to multiply 4 by 3v+1.
14v-8+4=-2\left(v+9\right)
Combine 2v and 12v to get 14v.
14v-4=-2\left(v+9\right)
Add -8 and 4 to get -4.
14v-4=-2v-18
Use the distributive property to multiply -2 by v+9.
14v-4+2v=-18
Add 2v to both sides.
16v-4=-18
Combine 14v and 2v to get 16v.
16v=-18+4
Add 4 to both sides.
16v=-14
Add -18 and 4 to get -14.
v=\frac{-14}{16}
Divide both sides by 16.
v=-\frac{7}{8}
Reduce the fraction \frac{-14}{16} to lowest terms by extracting and canceling out 2.
