If I was to solve these equations by using cramers rule would I lay it out like the below matrix?

1/180V1 - 1/1800V2 = 0.005

-1/1800V1 + 41/36000V2 - 1/2400V3 = 16/6000

-1/2400V2 + 1/1500V3 = 6/12000

\begin{bmatrix}1/180&-1/1800&0\\-1/1800&41/36000&-1/2400\\0&-1/2400&1/1500\end{bmatrix}.

\begin{bmatrix}1/180&-1/1800&0\\-1/1800&41/36000&-1/2400\\0&-1/2400&1/1500\end{bmatrix}.
