But don't know how to get the above format. The split environment will align these smaller parts. You can also use cases in equations â¦ to tell the TeX input processor to use the AMS numbering rules (where only certain environments produce numbered equations, as they would be in LaTeX). \begin{align} \label{eq:lnnonspbb} \lambda_i + \mu_i = 0 \\ \mu_i \xi_i = 0 \\ \lambda_i [y_i (w^T x_i + b) - 1 + \xi_i] = 0 \end{align} only label the first equation and only the first equation can be referred later.

For example, in the case of an article in A4 format of size 10 points: \documentclass[a4paper,10pt,fleqn]{article} \begin{document} \begin{eqnarray} 7x + 4y & = & 0 \\ 2x - 5y & = & 0 \end{eqnarray} It is also possible to set the tagging to âallâ, so that every displayed equation will get a number, regardless of the environment used. formulas, graphs). LaTeX forum â Math & Science â How to number equations in cases. Otherwise, use equation* (with an asterisk (*) symbol) if you need equations without the line number.. As shown in the example above, utilize the split environment if you would like to split the equations into smaller parts.
