Step-by-step explanation:
Invertible matrix are those matrix which are square matrix or non singular matrix.

0.
But for the question given above we cannot find determinant of matrix A as it is not square matrix. so inverse of given matrix does not exist. so it is not possible to have non trival solutions.
