linear algebra hw, thank you

If the equation Ax= 0 has only the trivial solution, then A is row equivalent to the
nxn identity matrix.

False; by the Invertible Matrix Theorem if the equation Ax = 0
has only the trivial solution, then the matrix is not invertible; this means the columns
of A do not span Rn. Thus, A must also be row equivalent to the nxn identity matrix.

Rn. Thus, A must also be row equivalent to the nxn identity matrix.
С.
False; by the Invertible Matrix Theorem if the equation Ax= 0 has only the
trivial solution, then the matrix is not invertible. Thus, A cannot be row equivalent to
