-12v+18+3v=5\left(v+2\right)
Use the distributive property to multiply -2 by 6v-9.
-9v+18=5\left(v+2\right)
Combine -12v and 3v to get -9v.
-9v+18=5v+10
Use the distributive property to multiply 5 by v+2.
-9v+18-5v=10
Subtract 5v from both sides.
-14v+18=10
Combine -9v and -5v to get -14v.
-14v=10-18
Subtract 18 from both sides.
-14v=-8
Subtract 18 from 10 to get -8.
v=\frac{-8}{-14}
Divide both sides by -14.
v=\frac{4}{7}
Reduce the fraction \frac{-8}{-14} to lowest terms by extracting and canceling out -2.
