if i have

Ax = B

where A is a 3x2 matrix

how do i find a 2x3 F so that FA = I?

i thought of postmultiplying both sides by inverse of A but A is non-square XD

i found out that its the left inverse, so far i got this

2a - b + 3c a - b + 2c = 1 0

2d - e + 3f d - e + 2f 0 1

2 equations 2 unknowns?
