A matrix proof is provided in the solution.

Solution Preview

We say that the matrices A and C are row-equivalent if one can be obtained from the other by a succession of operations of the following kinds:

1-interchanging two rows;

2-multiplying a row by a non-zero constant;

3-replacing a row by the sum of it and (a non-zero multiple of) another ...
