Answer
Infinitely many solutions.
Work Step by Step
The given equation is
$\Rightarrow 12y+6= 6(2y+1)$
Use distributive property.
$\Rightarrow 12y+6= 12y+6$
Subtract $12y$ from each side.
$\Rightarrow 12y+6-12y= 12y+6-12y$
Simplify.
$\Rightarrow 6= 6$
The statement $6=6$ is always true. so, the equation has infinitely many solutions.
