Aligning and numbering equations in LaTeX

[shomuban]

I have not been able to find any help for the following problem. I have two equations of the type


blahbli=0 j=1,2,..., S
blahbla=0 k=1,2,..., T

where I want the first and second equal signs on each line to line up vertically with the corresponding equal signs on the second line AND I want to assign a single equation number to the pair of equations. I tried

\begin{equation}
\begin{split} blahbli &=0 \qquad j=1,2,\ldots, S\\
blahbla &=0 \qquad k=1,2,\ldots, T.
\end{split}
\end{equation}

but that does not align the second equal sign and looks ugly. Any way around this? Appreciate your help!

Use aligned rather than split.

$$\begin{aligned} blahbli &=0 &j&=1,2,\ldots, S\\ blahbla &=0&k&=1,2,\ldots, T. \end{aligned}$$

Thank you so much! I had never used the aligned command before.
