Cramer's rule - Wikipedia, the free encyclopedia
Cramer's rule is a theorem in linear algebra, which gives the solution of a system of linear equations or corresponding square matrices in terms of determinants. It is named after Gabriel Cramer (170...
en.wikipedia.org/wiki/Cramer's_rule
   The Cramer of the rule is Gabriel Cramer (1704-1752), a Swiss mathematician who was a professor of mathematics at Geneva. When Cramer published his rule in 1750 he did not use determinants as they are now shown, and he gave no explanation for how he achieved the result.
