To find a matrix with a right inverse but no left inverse, we will consider a non-square matrix with more columns than rows. This matrix will have full row rank ...
Finding all left inverse of a matrix B
https://math.stackexchange.com
The matrix has several left inverses if it has more rows than columns, and it has zero left inverses if it has more columns than rows.
Invertible matrix
https://en.wikipedia.org
If A is m-by-n and the rank of A is equal to n, (n ≤ m), then A has a left inverse, an n-by-m matrix B such that BA = In. If A has rank m (m ≤ n), then it has ...

Well since det(B)≠0 then an inverse exists. You could multiply both sides by the inverse. Alternatively since B is not a zero divisor (since ...
Understanding matrix inverses

A left inverse allows us to find the representation of ˆy – a component of y in C(A) – in the column basis of A. These components are oblique projections onto C ...
