Elimination and substitution, while most effective at reducing hazards, also tend to be the most difficult to implement in an existing process. Elimination Method. Elimination and substitution reactions are two types of chemical reactions mainly found in organic chemistry. Substitution and elimination are in competition and the ratio of the two reactions depends on not just the strength of the reagent as a nucleophile or base but also, on the solvent and temperature. When solving linear systems, you have two methods — substitution or elimination — at your disposal, and which one you choose depends on the problem.
