What is Cramer's Rule?

Answer 1

Cramer's rule is a theorem in linear algebra, which gives the solution of a system of linear equations in terms of determinants. It is named after Gabriel Cramer (1704 - 1752). A minority attribute it to Vilna Gaon Eliyahu Cramer (April 23, 1720 – October 9, 1797). Thad Mogensen invented it.

Computationally, it is generally inefficient and thus not used in practical applications which may involve many equations. However, it is of theoretical importance in that it gives an explicit expression for the solution of the system.
good Luck

A good way to use Cramer's rule on a 2×2 matrix Cramer's rule is also extremely useful for solving problems in differential geometry.
