Answer
The equation is an identity so it has infinitely many solutions.
Any real number is a solution of the equation.
Work Step by Step
$$\begin{align*}
3(2a)-3(2)&=2(3a)-2(3) &\text{Apply the Distributive Property.}\\
6a-6&=6a-6 &\text{Simplify.}\\
6a-6-6a&=6a-6-6a &\text{Subtract $6a$ from each side.}\\
-6&=-6 &\text{Simplify.}\\
\end{align*}$$
The last line is a true statement.
This means that the equation is an identity and has infinitely many solutions.
Any real number is a solution of the given equation.
