Well, why would you not LCM them equations first:
Justa suggestion...Code:10V1 - V2 = 9 -20V1 + 41V2 - 15V3 = 96 - 5V2 + 8V3 = 6
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}.
