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:



begin{equation}
delta(x)equivleft{allbegin{aligned}
0,quad
text{if};xne 0\
infty,quad
text{if}; x=0
end{aligned}right}quad
text{with}quadint_{-infty}^{+infty}delta(x);dx=1.
end{equation}


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