To number the equations on the right, we use the argument fleqn in the class of the document: \documentclass. \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. Cases in Equations . You can also use cases in equations â¦ 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} From OeisWiki.
