I have inserted numbers in place of i and j, and have successfully deduced the value of β as a coefficient. However, i am unsure why we must have that equation if we know $Abegin{bmatrix}i\jend{bmatrix}=0$.

This question is very unclear - it in not clear what your vectors have to do with $Ax=B.$ What do you mean "you must have?"

If "$Abegin{bmatrix} i \ jend{bmatrix}= 0$" and "$Ax= B$" then $Aleft(x+ beta begin{bmatrix} i \ jend{bmatrix}right)= Ax+ beta Abegin{bmatrix} i \ j end{bmatrix}= B$ for any $beta$. Is that what you are asking?
