Thank you for your response,
I mean I’d like to increase spacing between multiple different lines, not within the same line. For example:
$$
\begin{aligned}
&\lim_{ x \to 1 } \frac{x^2-3x+2}{x^2-1} \\
=&\lim_{ x \to 1 } \frac{(x-2)(x-1)}{(x+1)(x-1)} \\
=&\lim_{ x \to 1 } \left(\frac{x-2}{x+1},x\neq 1\right) \\
=&\frac{(1)-2}{(1)+1} \\
=&-\frac{1}{2}
\end{aligned}
$$
I can change it to this by adding an additional “\\” after each line, but again, I then find the spaces too large. I’d like to find a middle ground.
Edit: the reason I want larger spaces, is if I have multiple lines of rational expressions it gets very hard to read. Here’s an example:
