Abstract
A matrix has an ordinary inverse only if it is square, and even then only if it is nonsingular or, in
other words, if its columns (or rows) are linearly independent. In recent years needs have been felt in
numerous areas of applied mathematics for some kind of partial inverse of a matrix that is singular
or even rectangular. In this paper, some results on the Quasi-commuting inverses, are given and
the effect of them in solving the case of linear system of equations where the coeffcient matrix is a
singular matrix, is illustrated.
