I want to set a counter in the following two lines (to the right)
\[
\left\{
\begin{aligned}
& u_t = H(x,t,Du)&\text{ in }& \mathbb{R}^n\times (0,T) \\\\
& u(x,0)=u_0(x) & \text{ in } &\mathbb{R}^n
\end{aligned}
\right.
\]
the problem is that I cannot add a counter in aligned environment and I cannot use an equation environment inside mathmode.

environment. Also it's pointless to loadamsmath
asempheq
loadsmathtools
which loads it:
