You have the equations:

You want this in the form

<-- I'm using a B to distinguish this from b.

So in the equations put all the Y, C, and T terms on the LHS and everything else on the right:

Now arrange the variables Y, C, T in that order in the equations. If a term doesn't exist, give it a 0 coefficient:

Now you should be able to verify that

You have the matrix equation:

Cramer's rule says that

I'll let you work the determinants. For verification I get that:
