  • Oct 27, 2020 · Cramer’s rule: In linear algebra, Cramer’s rule is an explicit formula for the solution of a system of linear equations with as many equations as unknown variables.It expresses the solution in terms of the determinants of the coefficient matrix and of matrices obtained from it by replacing one column by the column vector of the right-hand-sides of the equations.
  • Evaluating each determinant (using the method explained here), we get:. Cramer's Rule says that x = D x ÷ D, y = D y ÷ D, and z = D z ÷ D.That is: x = 3 / 3 = 1, y = -6 / 3 = -2, and z = 9 / 3 = 3. That's all there is to Cramer's Rule. To find whichever variable you want (call it "ß" or "beta"), just evaluate the determinant quotient D ß ÷ D.
