That's not Cramer's rule Suppose I have the following system of equations \[a1x+b1y=c1\] and \[a2x+b2y=c2\] Then x and y are given as \[x=\frac{\left[\begin{matrix}c1 & a1 \\ c2& a2\end{matrix}\right]}{\left[\begin{matrix}a1 & b1 \\ a2& b2\end{matrix}\right]}\] \[y=\frac{\left[\begin{matrix}b1 & c1 \\ b2& c2\end{matrix}\right]}{\left[\begin{matrix}a1 & b1 \\ a2& b2\end{matrix}\right]}\] All are determinants, can you find x and y?
