Answer:
(Transpose(A) A)X=Transpose(A)B
Explanation:
If the purpose of inverting the non-square matrix A is to solve a system of linear equations like Ax=B then you can multiply both sides of the matrix equation by the transpose of A so that it becomes (Transpose(A) A)X=Transpose(A)B. You can now invert Transpose (A) A and thus solve the system of equations
