Question

tell me Cramer's rule !!fast

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 implemented in a naïve way is computationally inefficient for systems of more than two or three equations.

• 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.
