Let A and I be as follows.(adsbygoogle = window.adsbygoogle || []).push({});

A = [1 d]

[c b]

I=[1 0]

[0 1]

Prove that if b - cd != 0, then A is row equivalent to I

I'm CLUELESS as to WHERE TO START. Please help me

I tried simplifying to the matrix

[1 d]

[0 b - cd]

And have no clue what to do next.
