I have four equations which I want to split, align and make sure there is a space between the equations.
\begin{align*}
\sum^\infty_{i=1} (3t_{2i-1}+t_{2i})9^{-i} \\
=\sum^\infty_{i=1} (3t_{2i-1}+t_{2i})3^{-2i}\\
= \sum^\infty_{i=1} 3^{-(2i-1)} t_{2i-1} + 3^{-2i} t_{2i}\\
=\sum^\infty_{i=1} t_i 3^{-i}
\end{align*}
I tried using the align
environment, but it aligns to the right.
I tried using flalign
but this leaves no space between the equations.
\end{align*}

which is what marks the division between the left-hand side of an equation and the right-hand side. you need to read some elementary documentation. trytexdoc amsmath
, for example. – barbara beeton Jul 17 '16 at 1:34
