You can use cases to simplify it a little bit and, of course, remove all as @siracusa said.
documentclass{article}
usepackage{amsmath}
begin{document}
begin{equation}
delta(x)equivleft.begin{cases}
0, & text{if } x ne 0 \
infty, & text{if } x = 0
end{cases}right}, quadtext{with } int_{-infty}^{+infty}delta(x); dx = 1.
end{equation}
end{document}

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?)
documentclass{article}
usepackage{amsmath} % for 'aligned' environment
begin{document}
begin{equation}
delta(x)equiv
left{
begin{aligned}
0, quad&text{if $xne 0$}\
infty,quad&text{if $x=0$}
end{aligned}
right},,
qquadtext{with }
int_{-infty}^{+infty}! delta(x),dx=1.
