## Homework Statement

A=(2 3, 1 2, 2 5) where the coma separates the rows of the matrix.

Does there exist a matric C such that AC=I? Where I is the 3x3 identity matrix.

**2. The attempt at a solution**

No. First I note that if it exists then C is a 2x3 matrix. I also note that if AC=I, then C is the inverse of A. But as A is not a square matrix, it doesn't have an inverse, so C cannot exist.

Am I right?
