Question

WHAT IS CRAMER RULE??
EXPLAIN WITH DIAGRAM. ​

Answer 1

Answer:

This rule is based upon manipulation of determinants of the matrices associated with the numerical coefficients of your system.

This rule is based upon manipulation of determinants of the matrices associated with the numerical coefficients of your system.You just pick the variable you want to solve for, replace that variable's column of values in the coefficient determinant with the answer-column's values, evaluate that determinant, and divide by the coefficient determinant.

More than that and you´ll have better chances using reductions methods (row echelon form).

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. If we are solving for x, the x column is replaced with the constant column.
