x+y+z=2
2x-y-2z=-1
x-2y-z=1
Cramer's Rule is a mathematical technique used to solve a system of linear equations with the same number of variables. It provides a method for finding the unique solution to a system by expressing each variable as a ratio of two determinants. The rule is named after the Swiss mathematician Gabriel Cramer.
