the problem is one of inverse matrices. given \[AA^{-1} = A^{-1}A=I_x\] where x is the dimension of a square matrix, the rest should follow
Suppose A is an m n matrix and there exist matrices C and D such that CA = In and AD = Im. Prove that m = n and C = D.
\[X_{mn}Y_{kl}=Z_{ml}\] and \[n=m\] for any matrices X,Y Since \[I_n\] is a square matrix \A_{mn}C_{xy}=I_{n} \quad n=x,\text { and }m=y=n \]
\[A_{mn}C_{xy}=I_{n} \quad n=x,\text { and }m=y=n \]
sorry, and \[n=k\]
