Prove a consistent matrix is still consistent after row operations have been performed on it

1

If a row operation is done to a consistent linear system, the resulting system must be consistent.

How can I prove this if it is true?

Thanks

Row operations correspond to multiplication on the left by invertible matrices, thus the linear system must be consistent after a row operation. – 2017-01-24
