I am trying to generate the following equation:
enter image description here



I am working with an old file (I have not written it) that already has the following code for this equation:



beginequation
delta(x)equivleftallbeginaligned
0,quad
textif;xne 0\
infty,quad
textif; x=0
endalignedrightquad
textwithquadint_-infty^+inftydelta(x);dx=1.
endequation


But this code doesn't work. Do you know what is wrong with that?

You can use cases to simplify it a little bit and, of course, remove all as @siracusa said.



documentclassarticle
usepackageamsmath
begindocument

beginequation
delta(x)equivleft.begincases
0, & textif x ne 0 \
infty, & textif x = 0
endcasesright}, quadtextwith int_-infty^+inftydelta(x); dx = 1.
endequation

enddocument

    As @siracusa has already pointed out in a comment, the all directive should be removed. The only other significant change I recommend making to your code is adding & alignment points inside the aligned environment. (After all, why employ an algin environment if no alignment is performed?)



    enter image description here
