First let This is the matrix formed by the coefficients of the given system of equations Now let's calculate the the determinant of the matrix A to get Remember that theAnswer to Solve the following system of equations by the method stated Cramer's Rule 2x 3y 4z = 5, 3x 4y z = 12, 2x 3y 2z = 7 ByView Answer Answer c Explanation Generally, in large systems, excessive multiplicative operations are required which becomes very cumbersome to solve 3 Apply Cramer's rule to solve the following equations 3x y 2z = 3 2x – 3y –z = 3 X 2y z = 4 a) X = 1, y = 2, z = 1 b) X = 2, y = 1, z = 1 2 2x 3y=2 x-y/2=1/2 using cramer's rule
