I want to make a result like this one, but I have no clue. Please give me your suggest. Thank you a lot for your help.

P/s: Please tell me how to typeset equations in the same way like this... Sorry my bad English cannot give you all what I'm asking for.

The newcases macro of mathtools ought to have an easier interface; with the current one you can still define a bcases environment (b for Ã¢Â€ÂœbracketÃ¢Â€Â).

You should also consider the more standard cases environment (it uses a brace).

I use an aligned stack here only to emphasize that if the left hand side of the two rows had different widths (here they do not), the aligned forms would be the most appropriate.

documentclassarticle
usepackagetabstackengine
stackMath
begindocument
[
 left[alignCenterstackm=&4\m<&-5right.
]
enddocument

enter image description here

In terms of the OP's test case, I give two different vertical alignment options, in the form of "D" and "E".

You should also consider the more standard cases environment (it uses a brace).

Your test case can be improved:

The newcases macro of mathtools ought to have an easier interface; with the current one you can still define a bcases environment (b for Ã¢Â€ÂœbracketÃ¢Â€Â).

I use an aligned stack here only to emphasize that if the left hand side of the two rows had different widths (here they do not), the aligned forms would be the most appropriate.

In terms of the OP's test case, I give two different vertical alignment options, in the form of "D" and "E".
