Question: Setup Differential Equation into a Matrixform

I'm practicing with matrices in Maple, but I have a question. My question is, how do I set up the differential equation system on matrix form x '(t) = Ax (t) + B?

Here are the equations:

x'1(t) = x1(t) - x2(t) - 3

x'2(t) = 12x1(t) - 8x2(t) + 4


I've been looking around for some help sources, but the only one I could find is this. I tried to set it up like that, but didn't work, it gave me an error.

How should I set it up (using Maple commands)?
