La règle de Cramer (ou méthode de Cramer) est un théorème en algèbre linéaire qui donne la solution d'un système de Cramer, c'est-à-dire un système d'équations linéaires avec autant d'équations que d'inconnues et dont le déterminant de la matrice de coefficients est non nul, sous forme de quotients de déterminants.. En calcul, la méthode est moins efficace que la méthode …
