During preparing a note about elementary row operations, I did the following as similar as I had found through the site:



‎‎begin{pmatrix}

‎2‎‎ & 1 \ 

1 & -5\‎

3 & circled{7} 

end{pmatrix}‎

‎‎xrightarrow ‎{‎tfrac{-12}{2}‎R_1+ R_3‎mapsto ‎R_3}‎‎

begin{pmatrix}

‎2‎‎ & 1 \ 

1 & -5\‎

-21 & circled{5-‎}‎ 

end{pmatrix}


‎
Is it possible to do it as the picture?



enter image description here



I think, If I can do that, they will be illustrated nicely.

Accessing regular linux commands in Huawei's Dopra Linux

Image
4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell".
