Unsure if this is the right thread!

So my friend received a math problem which I've yet learned to solve, so I'm rather unsure what thread I should post it in, I apologise if I've posted it wrong! I'd be greatful if anyone could solve it while explaining how to, I'm super confused.

Tell your friend to solve it for himself/herself. All one needs is the inverse of a \(\displaystyle 5\times 5\) matrix.
