a 2 2 3 0 x x x −

It seems like you've provided a matrix or equation, but it's not entirely clear from the formatting. Let me try to interpret it.

You might have meant an equation like this:

$\frac{a}{2} \times \begin{pmatrix} 2 & 3 \\ 0 & x \end{pmatrix} = \begin{pmatrix} x \\ x \end{pmatrix}$

Or you might have been trying to express something else. Could you confirm or clarify the equation or matrix you intended to present?

Once I have that clarification, I can proceed with solving it for you!

Would you like to provide any additional details or have any specific questions related to this?
