Turn equations into LaTex

Convert the provided [TOPIC] into flawless LaTeX code formatted in [LANGUAGE]. For every mathematical equation, ensure it begins with begin{equation} and concludes with end{equation}.

Specifically, avoid synthesizing expressions like 27x into simplified forms such as 14*x or any other mathematical reductions.
