Question

Can the following
following system of linear
equations be solved by Cramer's rule ? If
yes, apply the rule to solve it. If the rule is
not applicable
the Gaussian
use
elimination method to solve the system: 4
3x + 2y = 3
2x + 3y = 2 - 4z
5x + 7y = 5

Answer 1

Answer:

Cramer's rule fails if the determinant of the coefficient array is zero, since you can't divide by zero. In this case the system of equations is either inconsistent (it has no solutions) or it has infinitely many solutions. Either way, you need to use some other method to seek the solutions.
