Answer
The equation has infinitely many solutions.
Work Step by Step
The given equation is
$\Rightarrow -3(4-2v)=6v-12$
Use distributive property.
$\Rightarrow -12+6v=6v-12$
Subtract $6v$ from each side.
$\Rightarrow -12+6v-6v=6v-12-6v$
Simplify.
$\Rightarrow -12=-12$
True.
Hence, the equation has infinitely many solutions.
