Question

can anyone explain Cramer rules of equation plzz​

Answer 1

Answer:

In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution. ... Cramer's rule can also be numerically unstable even for 2×2 systems.

Answer 2

Answer:

Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables. Consider a system of two linear equations in two variables. x=DxD=|c1b1c2b2||a1b1a2b2|,D≠0;y=DyD=|a1c1a2c2||a1b1a2b2|,D≠0
